Risk-management decision-making data from a community-based sample of racially diverse women at high risk of breast cancer: rationale, methods, and sample characteristics of the Daughter Sister Mother Project survey. Breast Cancer Res 2024; 26:8. [PMID: 38212792 PMCID: PMC10785448 DOI: 10.1186/s13058-023-01753-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 12/13/2023] [Indexed: 01/13/2024] Open
Abstract
BACKGROUND To understand the dynamics that limit use of risk-management options by women at high risk of breast cancer, there is a critical need for research that focuses on patient perspectives. Prior research has left important gaps: exclusion of high-risk women not in risk-related clinical care, exclusion of non-white populations, and lack of attention to the decision-making processes that underlie risk-management choices. Our objective was to create a more inclusive dataset to facilitate research to address disparities related to decision making for breast cancer risk management. METHODS The Daughter Sister Mother Project survey collects comprehensive information about the experiences of women at high risk of breast cancer. We collected novel measures of feelings about and reactions to cancer screenings; knowledge, barriers, and facilitators of risk-management options; beliefs related to cancer risk and risk management; and involvement with loved ones who had cancer. Eligible individuals were non-Hispanic white and non-Hispanic Black adult women who self-identified as having high risk of breast cancer and had no personal history of cancer. Between October 2018 and August 2019, 1053 respondents completed the online survey. Of these, 717 were confirmed through risk prediction modeling to have a lifetime breast cancer risk of ≥ 20%. Sociodemographic characteristics of this sample were compared to those of nationally representative samples of the US population: the 2019 Health Information National Trends Survey and the Pew Research Center report: Jewish Americans in 2020. RESULTS The sample of 717 women at objectively high risk of breast cancer was largely (95%) recruited from non-clinical sources. Of these respondents, only 31% had seen a genetic counselor, 34% had had genetic testing specific to breast cancer risk, and 35% had seen at least one breast or cancer care specialist. The sample includes 35% Black respondents and 8% with Ashkenazi Jewish ancestry. Although encompassing a substantial range of ages, incomes, and education levels, respondents are overall somewhat younger, higher-income, and more educated than the US population as a whole. CONCLUSIONS The DSM dataset offers comprehensive data from a community-based, diverse sample of women at high risk of breast cancer. The dataset includes substantial proportions of Black and Ashkenazi Jewish women and women who are not already in clinical care related to their breast cancer risk. This sample will facilitate future studies of risk-management behaviors among women who are and are not receiving high-risk care, and of variations in risk-management experiences across race and ethnicity.

Abstract
INTRODUCTION Bilateral prophylactic mastectomy (BPM) in women with a high risk of developing breast cancer has shown to provide the greatest risk reduction. Many surgical guidelines recommend the removal of the pectoral fascia (PF) in mastectomies; however, there is no evidence to support this statement. Reported wound-related complications following mastectomy include seroma, flap necrosis, infection and haematoma. Seroma causes discomfort and may delay the reconstructive procedures. Whether removal or preservation of the PF influences drain volume, seroma formation and other postoperative complications following BPM remains unclear. The aim of this study is to assess the impact of removal versus preservation of the PF on drain policy and seroma after BPM. METHODS AND ANALYSIS This is a double blinded, prospective, randomised controlled pilot study with a within-subject design. The inclusion criteria are women >18 years, presenting in the Academic Breast Cancer Centre Rotterdam, who are opting for BPM. Patients with a history or diagnosis of breast cancer are excluded. According to the sample size calculation based on the difference in total drain volume, a number of 21 eligible patients will be included. Randomisation will occur within the patient, which means PF preservation in one breast and PF removal in the contralateral breast. The primary study endpoint is total drainage volume. Secondary study outcomes include time to drain removal, number of needle aspirations, postoperative complications and length of hospital stay. ETHICS AND DISSEMINATION The study is approved by the Erasmus Medical Center Review Board (REC 2020-0431). Results will be presented during international conferences and published in a peer-reviewed academic journal. TRIAL REGISTRATION NUMBER NCT05391763; clinicaltrials.gov.

Cancer Prev Res (Phila) 2020; 14:455-462.

Abstract
With the growing technical ease and reduction in genetic screening costs, whole population BRCA screening may be a feasible option. Our objective was to investigate the cost effectiveness of whole population screening for BRCA mutations in Israel, for varying degrees of BRCA carrier state. Lifetime costs of whole female population screening for BRCA mutation carrier state versus nonscreening were compared using a Markovian process decision analysis model. Model parameters including ovarian and breast cancer risks were obtained from previously published data. Screening and other treatment-related costs were received from the Israeli Ministry of Health pricing list according to specified codes. Quality-adjusted life years were used for cost-effectiveness analysis. Sensitivity analysis was conducted to evaluate model uncertainties, specifically varying degrees of BRCA prevalence. Results show that whole population BRCA screening in Israel is cost effective across a wide range of BRCA prevalence rates with an incremental cost-effectiveness ratio of 81,493 new Israeli Shekels for a BRCA prevalence of 2.5%, increasing to 250,000 new Israeli Shekels for a 0.75% prevalence rate, per quality-adjusted life year gained. Discount rate and population BRCA prevalence and rate of risk reduction salpingo-oophorectomy are the most influential parameters in the model. Whole population screening for BRCA mutations should be offered as part of general health screening strategies by national medical insurance providers, even for non-Ashkenazi Jews. Our algorithm can be applied for other countries, adjusting local costs of screening and treatment. PREVENTION RELEVANCE: Whole population BRCA mutation screening in Israel is cost effective across a wide prevalence rate and should be offered as part of general health screening strategies by national medical insurance providers for cancer prevention.

Abstract
BRCA1 or 2 mutations result in higher cancer risk for breast cancer (BC) and epithelial ovarian cancer (EOC) for carriers than exists in the general population. Optimal breast imaging surveillance in these patients has not been well defined. An Institutional Review Board-approved, multi-institutional retrospective chart review was performed. Patients diagnosed with BRCA-associated EOC between 1990-2015 were identified; demographic and clinical data were collected and analyzed. 192 BRCA mutation–positive patients with EOC were identified. 16/192 (8.3%) women were diagnosed with BC following EOC, at a median of 50 (range 5-327) months following EOC diagnosis and median age 59.5 (45-84) years. Breast cancer was most commonly detected on mammogram 7/16 (44%) or clinical exam 7/16 (44%). 2/16 (12.5%) had occult BC found during risk-reducing mastectomy. 14 (88%) had early-stage (0-2) disease. At mean follow-up of 8.1 years, 6 (37.5%) patients with BC following EOC had died due to EOC. The risk of BC diagnosis following EOC in BRCA mutation carriers is low; most of these BCs are early stage and diagnosed with mammography or physical exam. Overall, survival in BRCA mutation carriers is dominated by EOC-related mortality. Breast cancer surveillance in BRCA mutation carriers following EOC should prioritize nonsurgical strategies.

Abstract
Familial breast cancer is estimated to account for 15-20% of all cases of breast cancer. Surveillance for familial breast cancer is well-established world-wide. However, this service does not exist in Jordan, due to the scarcity of information with regard to the genetic profiling of these patients, and therefore lack of recommendations for policy-makers. As such, patients with very strong family history of breast or ovarian cancers are not screened routinely; leading to preventable delay in diagnosis. Whole coding sequencing for BCRA1/BCRA2 using next-generation sequencing (NGS)/Ion PGM System was performed. Sanger sequencing were then used to confirm the pathogenic variants detected by NGS. In this study, 192 breast cancer patients (and 8 ovarian cancer cases) were included. The prevalence of recurrent pathogenic mutations was 14.5%, while the prevalence of newly detected mutations was 3.5%. Two novel pathogenic mutations were identified in BRCA2 genes. The common mutations in the Ashkenazi population used for screening may not apply in the Jordanian population, as previously reported mutations were not prevalent, and other new mutations were identified. These data will aid to establish a specific screening test for BRCA 1/BRCA2 in the Jordanian population.

Abstract
BACKGROUND The rate of risk-reducing bilateral mastectomy (RRBM) among cancer-free Israeli female BRCA1/BRCA2 mutation carriers was reportedly 13% in 2010. Current RRBM rates in Israel and factors seemingly associated with opting for RRBM were reevaluated. METHODS Israeli female cancer-free BRCA1/BRCA2 mutation carriers, who were followed at the high-risk clinic at Sheba Medical Center between January 2011 and April 2020 were eligible. Univariate Cox regression and log-rank test were used to study the crude association between potential predictors and performance of RRBM. RESULTS Overall, 427 cancer-free BRCA1 (n = 218) or BRCA2 (n = 209) mutation carriers were included. Median age at genotyping was 33.6 years (interquartile range 26.8-41.8 years), median follow-up 4.4 years (range 0.1-7.6 years). Overall, 41/427 (9.6%) participants underwent RRBM, all of them within 5 years of genotyping. Being married (HR-2.57, p = 0.017) and having a first degree relative with breast cancer (BC) (HR-2.19, p = 0.017) were positively associated with RRBM, whereas any previous benign breast biopsy was negatively associated (HR-0.48, p = 0.029) with performing RRBM. CONCLUSIONS RRBM is still infrequently elected by Israeli BRCA1/BRCA2 mutation carriers, with married women with one relative with BC who have not undergone previous breast biopsy more likely to opt for RRBM.

Abstract
There is limited information known about how women with pathogenic variants (PV) in moderate penetrance genes make decisions to manage their increased risk of breast cancer. This study analyzed factors that may impact decision-making surrounding management for increased breast cancer risk. Women with a PV in a moderate penetrance gene associated with increased risk for breast cancer were identified from an institutional database. Semi-structured, qualitative interviews were conducted to analyze decision-making factors. Themes were developed using deductive codes based on previous literature and inductive codes based on interviewee responses. The 16 participants (mean age = 55.9 years) included 12 women with a breast cancer diagnosis. Six women (37.5%) chose bilateral mastectomy (BM), and 10 women (62.5%) chose surveillance as management. Of the 12 women with a personal history of breast cancer, four chose to have BM (33.3%). Two women without a personal history of breast cancer chose to have BM (50.0%). Transcriptions revealed seven comprehensive themes, as well as themes unique to affected and unaffected women (Cohen's kappa = 0.80). Physician opinion was the only factor present in all interviews reported to influence risk management decision-making. Several themes were consistent with prior BRCA1/BRCA2 research (family history, risk perception, sibling influence, and physician opinions). Autonomy and insurance/finances were also important factors to participants. There were certain differences in decision-making factors between affected and unaffected women, such as partner influence. Results indicate an opportunity for providers to engage their patients in a decision-making process.

Abstract
The last twenty years have seen a complete change in society's attitude to the strategy of risk reduction of breast cancer in high-risk individuals by means of proactive mastectomy. Once termed 'prophylactic mastectomy', risk reducing mastectomy (RRM) was considered two decades ago not only extreme, but in some quarters almost unethical. RRM is now commonly undertaken in specialist breast units for women at high individual breast cancer risk, by virtue of an inherited breast cancer related gene mutation or from calculated high statistical risk from family history data, and the efficacy of RRM in reducing subsequent incident diagnoses of breast cancer has been published from a number of centres. RRM is offered routinely in conjunction with total breast reconstruction, using the whole range of reconstructive surgical techniques. The public announcement by the actor Angelina Jolie in 2013 that she had inherited and harboured a BRCA1 gene mutation, and was undergoing RRM and breast reconstruction to lower her intrinsic breast cancer risk, had a significant effect on public attitudes and perception. Whilst there are other means of lowering breast cancer risk by means of selective oestrogen receptor modulators, such as tamoxifen and raloxifene, their lowering effect on risk of breast cancer remains substantially less than that afforded by surgical removal of 'at risk' breast tissue. The progressive development and increasing sophistication of techniques of breast reconstructive surgery has paralleled the trend for more RRM surgery, and the substantial majority of women who opt for RRM choose immediate breast reconstruction.

Abstract
INTRODUCTION Increased knowledge of breast cancer risk factors may enable a paradigm shift from the current age-based mammographic screening programmes to a personalised risk-based approach. This would warrant a significant change in practice, yet the acceptability from a woman's perspective has never been systematically explored. In this systematic review, we inventoried and appraised studies of women's perceptions of risk-based breast cancer screening and prevention to identify factors associated with adopting this new paradigm. METHODS We searched Medline, Embase and PsycInfo to identify original articles in English containing perceptions of risk-based breast cancer screening and/or primary prevention of women with an average to above average risk of developing breast cancer. Qualitative data were systematically extracted and referenced against four theoretical models of preventative health behaviour adoption. RESULTS When considering the adoption of this novel screening and prevention programme, women carefully review their perceived susceptibility to breast cancer. Their decisions are based on a cost-benefit analysis of adopting lifestyle changes, chemoprevention, or prophylactic surgery, taking into account their perceived competence, individual autonomy, relatedness to others, and personal preference. The role of intent is limited when considering behavioural change. CONCLUSIONS Implementing risk-based breast cancer screening and prevention will require a multifactorial approach. The transition from theory to practice can be supported by developing evidence-based shared decision aids and family-oriented (genetic) counselling programmes.

Abstract
AIM To compare Australian and French perceptions of genetics and preferences regarding the return of incidental findings. METHODS Participants from the International Sarcoma Kindred Study received a survey at intake to cancer referral units. A total of 1442 Australian and 479 French individuals affected by sarcoma and their unaffected family members responded to four hypothetical scenarios depicting hereditary conditions of varying treatability and severity. RESULTS Australians' preference for the return of incidental findings was consistently higher than French for all scenarios. Country group differences were significant for two scenarios when individual characteristics were controlled through multivariable analyses. CONCLUSION Findings support the need for guidelines that are sensitive to sociocultural context and promote autonomous decision-making.

Motivators and barriers of tamoxifen use as risk-reducing medication amongst women at increased breast cancer risk: a systematic literature review. Hered Cancer Clin Pract 2017; 15:14.

Abstract
Background Selective estrogen receptor modulators, such as tamoxifen, reduce breast cancer risk by up to 50% in women at increased risk for breast cancer. Despite tamoxifen’s well-established efficacy, many studies show that most women are not taking up tamoxifen. This systematic literature review aimed to identify the motivators and barriers to tamoxifen use ‘s amongst high-risk women. Methods Using MEDLINE, PsycINFO, and Embase plus reviewing reference lists of relevant articles published between 1995 and 2016, 31 studies (published in 35 articles) were identified, which addressed high-risk women’s decisions about risk-reducing medication to prevent breast cancer and were peer-reviewed primary clinical studies. Results A range of factors were identified as motivators of, and barriers to, tamoxifen uptake including: perceived risk, breast-cancer-related anxiety, health professional recommendation, perceived drug effectiveness, concerns about side-effects, knowledge and access to information about side-effects, beliefs about the role of risk-reducing medication, provision of a biomarker, preference for other forms of breast cancer risk reduction, previous treatment experience, concerns about randomization in clinical trial protocols and finally altruism. Conclusions Results indicate that the decision for high-risk women regarding tamoxifen use or non-use as a risk-reducing medication is not straightforward. Support of women making this decision is essential and needs to encompass the full range of factors, both informational and psychological.

Very high uptake of risk-reducing salpingo-oophorectomy in BRCA1/2 mutation carriers: A single-center experience. Gynecol Oncol 2016; 143:113-119. [PMID: 27430397 DOI: 10.1016/j.ygyno.2016.07.104] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2016] [Revised: 06/09/2016] [Accepted: 07/12/2016] [Indexed: 10/21/2022]
Abstract
OBJECTIVE Risk-reducing salpingo-oophorectomy (RRSO) is the only effective surgical strategy to reduce the increased risk of epithelial ovarian cancer in BRCA1/2 mutation carriers. Given the long-term health consequences of premature surgical menopause, we need insight in uptake and timing of RRSO to guide us in improving healthcare. METHODS A single-center retrospective cohort study of BRCA1/2 mutation carriers diagnosed and counseled at the multidisciplinary Family Cancer Clinic of the Radboud university medical center in Nijmegen, The Netherlands, between 1999 and 2014. Descriptive statistics were used to analyze uptake and timing of RRSO. RESULTS Data of 580 BRCA1/2 were analyzed. The uptake of RRSO among mutation carriers who are currently above the upper limit of the recommended age for RRSO, is 98.5% and 97.5% for BRCA1 and BRCA2 mutation carriers, respectively. The vast majority undergoes RRSO ≤40 (BRCA1) or ≤45 (BRCA2) years of age, provided that mutation status is known by that age: 90.8% and 97.3% of BRCA1 and BRCA2 mutation carriers, respectively. CONCLUSIONS The uptake of RRSO among BRCA1/2 mutation carriers who were counseled at our Family Cancer Clinic is extremely high. High uptake might be largely attributed to the directive and uniform way of counseling by professionals at our Family Cancer Clinic. Given the fact that RRSO is often undergone at premenopausal age in our population, future research should focus on minimizing long-term health consequences of premature surgical menopause either by optimization of hormone replacement therapy or by investigating alternative strategies to RRSO.

Abstract
BACKGROUNDS Breast cancer is a global threat to all women, especially those having close relatives with breast cancer. Women who were caregivers to relatives with breast cancer are more vulnerable to stress caused by the perception of heightened risk of cancer. Because health measures and breast health are affected by cultural beliefs and social status, information about breast cancer should consider the cultural beliefs and values of the society. OBJECTIVES This study explored the experiences of Iranian women who were caregivers to relatives with breast cancer. METHODS In this qualitative content analysis study, 21 female caregivers of breast cancer patients were chosen by purposive sampling. Data were collected through interviews and analyzed using content analysis. RESULTS Data analysis developed 3 categories: perception of the concept of risk, changing views about femininity, and management of perceived threat. Perception of the risk of breast cancer increased in caregivers, and they tried to manage the perceived threat. They considered the breast to be an important part of women's lives, and breast cancer in relatives changed their view of femininity. CONCLUSION Understanding the experiences of breast cancer family caregivers in different cultures can help in planning, counseling, and effective intervention.

Abstract
BACKGROUND Tamoxifen has been US Food and Drug Administration-approved for primary prevention of breast cancer since 1998 but has not been widely adopted, in part because of increased risk of serious side effects. Little is known about the risk-benefit profiles of women who use chemoprevention outside of a clinical trial. We examined characteristics associated with initiation and discontinuation of tamoxifen for primary prevention of breast cancer within a large cohort of women with a first-degree family history of breast cancer. METHODS This research was conducted within The Sister Study, a cohort of 50884 US and Puerto Rican women age 35 to 74 years enrolled from 2003 to 2009. Eligible women were breast cancer-free at enrollment and had a sister who had been diagnosed with breast cancer. Participants reported tamoxifen use, ages started and stopped taking tamoxifen, and total duration of use at enrollment. We identified 788 tamoxifen users and 3131 nonusers matched on age and year of enrollment who had no history of contraindicating factors (stroke, transient ischemic attack, cataract, endometrial or uterine cancer). Characteristics associated with tamoxifen initiation were evaluated with multivariable conditional logistic regression. All statistical tests were two-sided. RESULTS Based on published risk-benefit indices, 20% of women who used tamoxifen had insufficient evidence that the benefits of tamoxifen outweigh the risk of serious side effects. After 4.5 years, 46% of women had discontinued tamoxifen. CONCLUSIONS While the majority of women who used tamoxifen for primary prevention of breast cancer were likely to benefit, substantial discontinuation of tamoxifen before five years and use by women at risk of serious side effects may attenuate benefits for breast cancer prevention.

Abstract
Western studies have shown that the uptake rates of surveillance and prophylaxis may vary among BRCA mutation carriers between ethnicities. The present study is the first to investigate the behavioural impact and subjective attitudes in Southern Chinese high-risk families who had undergone BRCA1 and BRCA2 genetic testing up to 2.5 years post-testing. Individuals who had such genetic testing and have consented to participate in the prospective database of Hong Kong Hereditary Breast Cancer Family Registry were recruited and surveyed by a face-to-face or telephone interview. Sociodemographic information, genetic test results, pre- and post-testing surveillance, medical regimes, and attitudes towards the choice of clinical management were obtained by interviews and retrieval of medical records using this prospective database. 69 females with breast cancer history were recruited into the study. Twenty-nine female carriers (15 BRCA1 mutated gene-carriers and 14 BRCA2 mutated gene-carriers) and 40 non-carriers of a BRCA 1/2 mutations were interviewed. The uptake rate of high risk breast screening i.e. clinical breast examination, mammography, and breast MRI is significantly higher among female carriers (48.3 %) after knowing genetic testing results than before (p < 0.01). A strong significant relationship between any increase or decrease of ovarian ultrasound screening (OS) and genetic status is found (p < .001), with more females did OS and with a higher frequency after knowing genetic testing results among both carriers (22.7 % → 86.4 %) and non-carriers (37.5 % → 50.0 %). Among carriers, very few opted for prophylactic surgeries. The present cohort might see prophylaxis as last resort and would use traditional Chinese medicine in cancer risk management.

Abstract
The diagnostic and local treatment modalities of hereditary breast cancer (HBC) are evolving based on emerging evidence from new imaging, radiotherapy and surgical studies. The optimal selection of diagnostic and therapeutic strategies for the individual HBC patient remains an area of active research in this relatively new patient population. In this context, some rational pathways of intervention are currently available to both reduce cancer risk in mutation carriers without a cancer diagnosis, as well as to reduce the risk of recurrence or new cancers among the carriers already diagnosed with a malignancy. It is encouraging to notice to what degree certain interventions have successfully reduced both the risk of malignancy and the anxiety associated with this genetic diagnosis. This updated report aims at summarizing the most recent findings, while it identifies the areas of uncertainty that remain, and continue to present difficult challenges, particularly among younger HBC patients.

Abstract
We explored the experiences of Ashkenazi Jewish and French Canadian women and meanings attributed to their hereditary breast and ovarian cancer (HBOC) risk. We purposively sampled 40 BRCA1 or BRCA2 (BRCA) mutation carriers and conducted theoretically driven semistructured interviews. According to content analysis, participants from these two ethnocultural groups held divergent meanings associated with being a BRCA carrier and different views pertaining to the illness experience and risk awareness. All participants identified a genetic basis; however, the French Canadian women also expressed other causes. The French Canadian women reported not knowing other carriers in their social environment, whereas the Ashkenazi Jewish women emphasized a strong sense of community contributing to their ethnic risk awareness. Based on these findings, we suggest that French Canadian women could benefit from greater awareness of the HBOC genetic risk and that health care providers should consider ethnically related and individual-based experiences and meanings during counseling.

Abstract
With the completion of the Human Genome Project and the development of high throughput technologies, such as next-generation sequencing, the use of multiplex genetic testing, in which multiple genes are sequenced simultaneously to test for one or more conditions, is growing rapidly. Reflecting underlying heterogeneity where a broad range of genes confer risks for one or more cancers, the development of genetic cancer panels to assess these risks represents just one example of how multiplex testing is being applied clinically. There are a number of issues and challenges to consider when conducting genetic testing for cancer risk assessment, and these issues become exceedingly more complex when moving from the traditional single-gene approach to panel testing. Here, we address the practical considerations for clinical use of panel testing for breast, ovarian, and colon cancers, including the benefits, limitations and challenges, genetic counseling issues, and management guidelines.

Abstract
Studies suggest that patients carrying a BRCA variant of uncertain significance (VUS) may have lingering confusion concerning results interpretation. Counseling for uninformative BRCA-negative (UN) results is thought to be more straightforward, despite the fact that both results lead to similar methods of empiric cancer risk counseling. This study compared surgical choices and perceptions between 71 patients with VUS results and 714 patients with UN results. All patients underwent genetic counseling because of a personal or family history of breast or ovarian cancer between 1997 and 2010, and completed a 2-year follow-up survey. Risk-reducing mastectomy rates in both groups were 7% (p = 1.00) and risk-reducing oophorectomy rates were 5% and 3%, respectively (p = 0.42). The VUS group reported less cancer distress reduction than the UN group (23.0% vs 35.8%, respectively, p = 0.043). Over 90% of both groups found the counseling process helpful. Overall, the study suggests that VUS results disclosed in genetic counseling did not cause excessive surgery or exaggerated cancer distress, though patients with a VUS found counseling somewhat less informative or reassuring. Future research on communication of VUS results, including pre-and post-test counseling, is essential for full realization of the potential for genomic medicine.

Abstract
PURPOSE Prophylactic mastectomy (PM) has proven to be the most effective method to reduce the risk of breast cancer in high-risk women. The present study aimed to present and compare the attitudes towards PM among physicians in France, Germany, the Netherlands and the United Kingdom (UK). PATIENTS AND METHODS An international sample of 1196 general practitioners (GPs) and 927 breast surgeons (BS) were surveyed using a mailed questionnaire. RESULTS Only 30% of the French and 27% of the German GPs were of opinion that PM should be an option for an unaffected female BRCA1/2 mutation carrier, as compared to 85% and 92% of the GPs in the Netherlands and UK, respectively. Similarly, 78% of the French and 66% of the German BS reported a positive attitude towards PM, as compared to 100% and 97% of the BS in the Netherlands and UK, respectively. In the whole sample of GPs, a positive attitude towards PM was associated with country of residence, being female, and having more knowledge of breast/ovarian cancer genetics, while among BS there was a positive association with country of residence and having more knowledge of breast/ovarian cancer genetics as well, and, in addition, with a higher number of newly diagnosed breast cancer patients last year. CONCLUSION These results demonstrated the international variations in the attitude towards PM among physicians. This might reflect that different policies are adopted to prevent breast cancer in women at-risk.

Abstract
UNLABELLED Prophylactic mastectomy is an effective, although controversial strategy to reduce the risk of breast cancer in women carrying a BRCA1/2 mutation. A multidisciplinary pre- and post-operative clinical management is recommended for women who consider or undergo this surgery, because of its radical and irreversible nature as well as its possible impact on quality of life. OBJECTIVE This study aims to report on the experience of patients having undergone prophylactic mastectomy within a medical setting offering such a clinical management. METHODS A retrospective qualitative study was conducted with patients having had a prophylactic mastectomy between 2002 and 2006 at the centre des maladies du sein Deschênes-Fabia (CMSDF) in Quebec City. Fifteen women were interviewed and the narratives were analyzed using thematic content analysis method. RESULTS The participants generally appreciated the multidisciplinary approach that was used at the CMSDF and believed it was necessary. Improvements were suggested regarding information and post-surgical medical follow-up, some of which are now implemented. CONCLUSION The study results confirm the utility and the acceptability of a multidisciplinary clinical follow-up for women who undergo prophylactic mastectomy.

Abstract
Chemoprevention for women at risk for breast cancer has been shown to be effective, but in actual practice, women's uptake of chemoprevention has been poor. We explored factors that influence acceptability, adherence, and dropout in the International Breast (Prevention) Intervention Study during our first 3 years of activity at the Modena Familial Breast and Ovarian Cancer Center. We evaluated socio-demographic characteristics, health status, adherence, and side effect intensity. Semi-structured interviews analyzed reasons for accepting/refusing/stopping the trial. A total of 471 postmenopausal women were invited to participate, of which 319 declined to participate (68%), 137 accepted to participate (29%), and 15 participants did not make a final decision (3%). Breast cancer-related worries and trust in our preventive and surveillance programs were the most frequent reasons for accepting. Side effect-related worry was the most frequent reason for refusing. General practitioners' and family members' opinions played an important role in the decision-making process. Adherence significantly decreased after a 12-month follow-up, but it remained unchanged after 24- and 36-month follow-ups. Mild/moderate side effects reported by women did not change after 12 months of treatment. Forty percent of women withdrew from the study due to complaints of side effects. We concluded that chemoprevention trials are difficult medical experiments and that the process of deciding about whether or not to participate is based mainly on beliefs and values. This study has important clinical implications. During counselling with prospective participants, it is important to emphasize the potential benefits and to promote an informed choice. How participants make decisions, their belief systems, and their perception of risk are all factors that should be investigated in future research.

Abstract
About one in 300 women will be diagnosed with breast cancer before the age of 40. Advances in screening have not had an impact on mortality in women who are too young to be candidates for screening. Risk factors for early breast cancer include a lean body habitus and recent use of an oral contraceptive. Breast cancers in very young women are typically aggressive, in part owing to the over-representation of high-grade, triple-negative tumours, but young age is an independent negative predictor of cancer-specific survival. Very early age-of-onset also correlates strongly with the risk of local recurrence and with the odds of contralateral breast cancer. Given the high risks of local and distant recurrence in young women with invasive breast cancer, most (if not all) young patients are candidates for chemotherapy. It is hoped that by increasing breast cancer awareness, the proportion of invasive breast cancers that are diagnosed at 2.0 cm or smaller will increase and that this will lead to a reduction in mortality.

Abstract
BACKGROUND The recognition of an inherited component to breast cancer has led to an increase in demand for information, reassurance, and genetic testing, which has resulted in the creation of genetic clinics for familial cancer. The first step for patients referred to a cancer genetic clinic is a risk assessment. OBJECTIVES To evaluate the impact of cancer genetic risk-assessment services on patients at risk of familial breast cancer. SEARCH METHODS The specialised register maintained by the Cochrane Breast Cancer Group was searched on 16th February 2005. We also searched MEDLINE, EMBASE, CINAHL, PsycLIT, CENTRAL, DARE, ASSIA, Web of Science, SIGLE and LILACS. The original searches covered the period 1985 to February 2005. We also handsearched relevant journals. For this review update the search was repeated through to April 2011. SELECTION CRITERIA We considered trials looking at interventions for cancer genetic risk-assessment services for familial breast cancer for inclusion. Trials assessed outcomes such as understanding of risk, satisfaction and psychological well-being. We excluded studies if they concerned cancers other than breast cancer or if participants were not at risk of inherited breast cancer. We also excluded trials concerning the provision of general cancer genetic information or education as this review was concerned with the delivery of genetic risk assessment. Participants could be individuals of any age or gender, with or without a known BRCA mutation, but without a previous history of breast cancer or any other serious illness. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Additional information was sought from investigators as necessary. Due to the heterogeneity of both the interventions and outcomes, we reported data descriptively. MAIN RESULTS In this review update, we included five new trials, bringing the total number of included studies to eight. The included trials (pertaining to 10 papers), provided data on 1973 participants and assessed the impact of cancer genetic risk assessment on outcomes including perceived risk of inherited cancer, and psychological distress. This review suggests that cancer genetic risk-assessment services help to reduce distress, improve the accuracy of the perceived risk of breast cancer, and increase knowledge about breast cancer and genetics. The health professional delivering the risk assessment does not appear to have a significant impact on these outcomes. AUTHORS' CONCLUSIONS This review found favourable outcomes for patients after risk assessment for familial breast cancer. However, there were too few papers to make any significant conclusions about how best to deliver cancer genetic risk-assessment services. Further research is needed assessing the best means of delivering cancer risk assessment, by different health professionals, in different ways and in alternative locations.

Abstract
BACKGROUND Mutations in the BRCA genes confer greater risk of developing breast, ovarian, and prostate cancer. Families carrying the mutation can have intensive surveillance and take preventative measures. This is the first report on the uptake of such interventions in Chinese mutation carriers residing in Asia. METHODS Breast and ovarian cancer index patients and family members referred for genetic counselling and testing who are found to carry the BRCA mutations were included in this multicenter study. RESULTS A total of 31 patients with breast and/or ovarian cancer were found to carry BRCA1 or BRCA2 mutations. Forty-one tested family members also carried the mutations. Of the females, 85.7% of the index patients opted for breast surveillance and 23.8% for prophylactic mastectomy. Of the family members, 82.4% chose breast surveillance and 17.7% had prophylactic mastectomy. The majority of index patients and family members preferred ovarian surveillance (84 and 82.4%). Amongst the index patients, 32% decided for prophylactic salpingo-oophorectomy; 17.6% of the family members who did not have history of ovarian cancer decided to have prophylactic salpingo-oophorectomy. All male index patients agreed to breast and prostate surveillance, including breast clinical examination and PSA monitoring. For those male family members found to be BRCA mutation carriers, 56.3% agreed to have breast surveillance and 66.7% agreed to have prostate surveillance. No index patient or family member agreed to any form of chemoprevention. CONCLUSIONS Chinese BRCA mutation carriers have a higher uptake of cancer surveillance than prophylactic surgery and have a lack of interest in the use of chemoprevention drugs.

Abstract
In a French national cohort of unaffected females carriers/non-carriers of a BRCA1/2 mutation, long-term preventive strategies and breast/ovarian cancer risk perceptions were followed up to 5 years after test result disclosure, using self-administered questionnaires. Response rate was 74%. Carriers (N=101) were younger (average age±SD=37±10) than non-carriers (N=145; 42±12). There were four management strategies that comprised 88% of the decisions made by the unaffected carriers: 50% opted for breast surveillance alone, based on either magnetic resonance imaging (MRI) and other imaging (31%) or mammography alone (19%); 38% opted for either risk reducing salpingo-oophorectomy (RRSO) and breast surveillance, based on MRI and other imaging (28%) or mammography alone (10%). The other three strategies were: risk reducing mastectomy (RRM) and RRSO (5%), RRM alone (2%) and neither RRM/RRSO nor surveillance (6%). The results obtained for various age groups are presented here. Non-carriers often opted for screening despite their low cancer risk. Result disclosure increased carriers' short-term high breast/ovarian cancer risk perceptions (P⩽0.02) and decreased non-carriers' short- and long-term perceptions (P<0.001). During follow-up, high breast cancer risk perceptions increased with time among those who had no RRM and decreased in the opposite case; high ovarian cancer risk perceptions increased further with time among those who had no RRSO and decreased in the opposite case; RRSO did not affect breast cancer risk perceptions. Informed decision-making involves letting women know whether opting for RRSO and breast MRI surveillance is as effective in terms of survival as RRM and RRSO.

Abstract
BACKGROUND Women who are notified they carry a BRCA1/2 mutation are presented with surgical options to reduce their risk of breast and ovarian cancer, including risk-reducing mastectomy (RRM) and risk-reducing oophorectomy (RRO). Growing evidence suggests that a sub-group of women do not make decisions about RRM and RRO immediately following genetic testing, but rather, consider these decisions years later. Women's perspectives on the timing of these decisions are not well understood. Accordingly, the purpose of this research was to describe how women construct the 'right time' to consider decisions about RRM and RRO. METHODS In-depth interviews were conducted with 22 BRCA1/2 carrier women and analyzed using qualitative, constant comparative methods. RESULTS The time that lapsed between receipt of genetic test results and receipt of RRM or RRO ranged from three months to nine years. The findings highlighted the importance of considering decisions about RRM and RRO one at a time. The women constructed the 'right time' to consider these decisions to be when: (1) decisions fit into their lives, (2) they had enough time to think about decisions, (3) they were ready emotionally to deal with the decisions and the consequences, (4) all the issues and conflicts were sorted out, (5) there were better options available, and (6) the health care system was ready for them. CONCLUSIONS These findings offer novel insights relevant to health care professionals who provide decision support to women considering RRM and RRO.

Abstract
PURPOSE Women at high risk of breast cancer face the complex decision of whether to take tamoxifen or raloxifene for breast cancer chemoprevention. We investigated what is known about decisions of women regarding chemoprevention. METHODS Using MEDLINE, CINAHL, and PSYCINFO, plus reviewing reference lists of relevant articles, in December 2009 we identified 13 studies that addressed patient decisions about breast cancer chemoprevention, were published in 1995 or later, were peer-reviewed primary clinical studies, and reported rates at which participants showed interest in (hypothetical uptake) or accepted (real uptake) chemoprevention medications. RESULTS Nine studies provided information about hypothetical breast cancer chemoprevention decisions (mean uptake rate, 24.7%) and five provided information about real decisions (mean uptake rate, 14.8%). The range of rates was wide, and each of the hypothetical uptake studies assessed interest differently. A logistic regression model found significant correlation with uptake of decision type (hypothetical versus real, odds ratio [OR] = 1.65; 95% CI, 1.26 to 2.16), educational or decision support intervention (provided v not, OR = 0.21; 95% CI, 0.17 to 0.27), and cohort risk for breast cancer (high-risk v general population, OR = 0.65; 95% CI, 0.56 to 0.75). Perceived vulnerability to breast cancer was consistently correlated with increased uptake, and concern for adverse effects was correlated with reduced uptake. All studies used a correlational/descriptive design, and most studies used convenience sampling strategies. CONCLUSION Breast cancer chemoprevention uptake rates are low and variation is wide. Hypothetical uptake rates are higher than real uptake, and interventions markedly reduce uptake. Research is needed that uses reproducible sampling methods and examines decision support strategies that lead to quality decisions.

Abstract
PURPOSE The uptake of risk-reducing surgery in women at increased risk of breast and ovarian cancer is highly variable between countries and centers within countries. We have investigated the rate, timing, and age of uptake of surgery in the northwest of England to report the results after up to 7 years in a Regional Genetics center. METHODS Uptake was documented in 211 known unaffected BRCA1/2 mutation carriers from 509 families and in 3,515 women at >25% lifetime risk of breast cancer without known mutations. RESULTS Of the 211 mutation carriers, 40% opted for bilateral risk-reducing mastectomy (BRRM) and 45% underwent bilateral risk-reducing salpingo-oophorectomy (BRRSPO). Uptake of BRRM was significantly related to lifetime risk and age but continued over several years. In women not known to carry a BRCA mutation, 6.4% of women at 40% to 45% lifetime risk, 2.5% of women at 33% to 39% lifetime risk, and 1.8% of women at 25% to 32% lifetime risk underwent BRRM (P < 0.005). BRRSPO uptake was greater in BRCA1 (52%) than BRCA2 (28%) carriers but in both groups tended to occur within the first 2 years after gene test (except in the youngest age group) and in women between the ages of 35 and 45. CONCLUSION To truly assess the uptake of risk-reducing surgery, longer-term follow-up is necessary particularly in younger women who are likely to delay BRRSPO. Careful risk counseling does seem to influence women's decisions for surgery, although the effect is not immediate.

Abstract
INTRODUCTION AND AIMS For women who carry BRCA mutations, risk-reducing surgeries are an option to decrease breast and ovarian cancer risk. This study aims to determine the uptake, time course, and predictors of risk-reducing mastectomy (RRM) and risk-reducing salpingo-oophorectomy (RRSO) in BRCA carriers. RESULTS In 272 female carriers, followed for a median of 3.7 years, 23% of those eligible chose RRM, and 51% percent chose RRSO. Among BRCA carriers who chose these procedures, median time to both RRM and RRSO was approximately 4 months after learning of BRCA-positive results. Predictors of RRM were as follows: age below 60 years (hazard ratio 1.8, p=0.04), prior breast cancer (hazard ratio 2.4, p=0.0004), and RRSO (hazard ratio 7.2, p<0.0001). Predictors of RRSO were as follows: age below 60 years (hazard ratio 3.6, p=0.006), prior breast cancer (hazard ratio 1.8, p=0.002), and RRM (hazard ratio 5.4, p<0.0001). CONCLUSIONS Many women who undergo BRCA testing use these results to make clinical decisions; those who choose risk-reducing surgeries typically do so within months of receiving BRCA-positive results. Predictors of risk-reducing surgery uptake include the following: age below 60 years, prior breast cancer, and utilization of another risk-reducing surgery. Future research directions include examining other preventive and screening options in BRCA carriers as well as studying motivations for choosing or declining risk-reducing surgeries.

Abstract
OBJECTIVE To analyse the level of adherence to prophylactic surgery of breast and/or ovarian cancer in female carriers of the BRCA1 or BRCA2 mutation in a referential genetic counselling unit in Spain. METHODS Between January 1998 and November 2006, a total of 684 families with several cases of breast and/or ovarian cancer were selected by the Genetic Counselling Unit at the Hospital Clínico Universitario San Carlos. Some of them opted for prophylactic surgery after genetic counselling and genetic testing. RESULTS The pathogenic mutation was found in 57 families out of a total of 449 families who fulfilled the hereditary breast/ovarian cancer criteria. Out of a total of 238 individuals who were carriers of the mutation, 136 (57%) were offered risk-reducing prophylactic surgery. Prophylactic surgery was chosen by 58 (43%) women out of a total of 136 who were offered this possibility; the histological findings observed 7% malignant lesions in the breast and, in the ovarian-fallopian complex, 2 cases (8%) of a borderline tumour and one case (4%) of papillary adenocarcinoma. CONCLUSION This is the first study published on the role of prophylactic surgery in BRCA mutation carriers in the Spanish population. The incidence of occult carcinoma in these cases is lower than in other series.

Abstract
Several options for cancer prevention are available for women with a BRCA1 or BRCA2 mutation, including prophylactic surgery, chemoprevention and screening. The authors report on preventive practices in women with mutations from 9 countries and examine differences in uptake according to country. Women with a BRCA1 or BRCA2 mutation were contacted after receiving their genetic test result and were questioned regarding their preventive practices. Information was recorded on prophylactic mastectomy, prophylactic oophorectomy, use of tamoxifen and screening (MRI and mammography). Two thousand six hundred seventy-seven women with a BRCA1 or BRCA2 mutation from 9 countries were included. The follow-up questionnaire was completed a mean of 3.9 years (range 1.5-10.3 years) after genetic testing. One thousand five hundred thirty-one women (57.2%) had a bilateral prophylactic oophorectomy. Of the 1,383 women without breast cancer, 248 (18.0%) had had a prophylactic bilateral mastectomy. Among those who did not have a prophylactic mastectomy, only 76 women (5.5%) took tamoxifen and 40 women (2.9%) took raloxifene for breast cancer prevention. Approximately one-half of the women at risk for breast cancer had taken no preventive option, relying solely on screening. There were large differences in the uptake of the different preventive options by country of residence. Prophylactic oophorectomy is now generally accepted by women and their physicians as a cancer preventive measure. However, only the minority of women with a BRCA1 or BRCA2 mutation opt for prophylactic mastectomy or take tamoxifen for the prevention of hereditary breast cancer. Approximately one-half of women at risk for breast cancer rely on screening alone.

Abstract
BACKGROUND The present study aimed to assess predictors of distress after 'prophylactic mastectomy (PM) and salpingo-ovariectomy (PSO), in order to enable the early identification of patients who could benefit from psychological support. PATIENTS AND METHODS General distress and cancer-related distress were assessed in 82 women at increased risk of hereditary breast and/or ovarian cancer undergoing PM and/or PSO, before and 6 and 12 months after prophylactic surgery. Neurotic lability and coping were assessed before surgery. RESULTS Cancer-related distress and general distress at both follow-up moments were best explained by the level of cancer-related and general distress at baseline. Being a mutation carrier was predictive of increased cancer-related distress at 6-month follow-up (but not at 12 months), and of lower general distress 12 months after prophylactic surgery. Also, coping by having comforting thoughts was predictive of less cancer-related distress at 6-month follow-up. CONCLUSIONS Genetically predisposed women who are at risk of post-surgical distress can be identified using one or more of the predictors found in this study. Exploration of and/or attention to cancer-related distress and coping style before prophylactic surgery may help physicians and psychosocial workers to identify women who might benefit from additional post-surgical support.

Abstract
BACKGROUND The recognition of an inherited component to breast cancer has led to an increase in demand for information, reassurance, and genetic testing, resulting in the creation of genetics clinics for familial cancer. The first step for patients referred to a cancer genetic clinic is a risk assessment. OBJECTIVES To evaluate the impact of cancer genetic risk assessment services on patients at risk of familial breast cancer. SEARCH STRATEGY The specialised register maintained by the Cochrane Breast Cancer Group was searched. We also searched MEDLINE, EMBASE, CINAHL, PsycLIT, CENTRAL, DARE, ASSIA, Web of Science, SIGLE and LILACS. The searches covered the period 1985 to February 2005. We also hand-searched relevant journals. SELECTION CRITERIA Trials looking at interventions for cancer genetic risk assessment delivery for familial breast cancer were considered for inclusion. Trials assessed outcomes such as understanding of risk, satisfaction and psychological well-being. Studies were excluded if they concerned cancers other than breast cancer or if participants were not at risk of breast cancer. Trials concerning the provision of information or education were also excluded as it was intended to review these separately. Participants could be individuals of any age or gender, with or without a known BRCA mutation, but without a previous history of breast cancer or any other serious illness. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. Additional information was sought from investigators as necessary. Due to the heterogeneity of both the interventions and outcomes, data were analysed descriptively. MAIN RESULTS Fifty-eight papers were identified as relevant to the review, 54 of these were subsequently excluded. The three included trials (pertaining to five papers), provide data on 1251 participants and assessed the impact of cancer genetic risk assessment on outcomes including perceived risk, and psychological distress. This review suggests that cancer genetic risk assessment services help to reduce distress, improve the accuracy of the perceived risk of, and increase knowledge about, breast cancer and genetics. The health professional delivering the risk assessment does not appear to have a significant impact on these outcomes. AUTHORS' CONCLUSIONS This review found favourable outcomes for patients' risk assessment for familial breast cancer. However, there were too few papers to make any significant conclusions about how best to deliver cancer genetic risk assessment services. Further research is needed assessing the best means of delivering cancer risk assessment, by different health professionals, in different ways and in alternative locations.

Abstract
BACKGROUND Women who are at increased risk for breast and ovarian cancers, especially BRCA1 and BRCA2 mutation carriers, face a myriad of risk-reduction options, including increased surveillance, chemoprevention, prophylactic oophorectomy, and prophylactic mastectomy. However, little is known about which clinical, demographic, or cancer-related factors are associated with risk-reduction interventions. METHODS The authors conducted a retrospective review of records for 554 women who had undergone testing at The University of Texas M. D. Anderson Cancer Center between 2000 and 2006 for deleterious BRCA1 and BRCA2 gene mutations. Data were collected on the risk-reduction interventions these women adopted after they underwent genetic testing. These data were tested for associations with demographic and clinical characteristics. RESULTS Among the 554 women who underwent genetic testing for BRCA mutation, 78 were found to have a deleterious mutation in the BRCA1 gene, and 54 had a mutation in the BRCA 2 gene. Of the 554 women, 85 underwent prophylactic mastectomy, 30 prophylactic oophorectomy, and 52 both surgeries; 387 women opted for surveillance. Women who had BRCA mutations, a history of breast cancer or ductal carcinoma in situ (DCIS), or previous breast biopsies were more likely to have prophylactic surgery. Women with a family history of ovarian cancer were more likely to undergo prophylactic oophorectomy. Women with a personal history of ovarian cancer or advanced breast cancer were more likely to undergo surveillance only. Women with breast cancer who had had a total mastectomy as part of their prior breast cancer treatment underwent prophylactic mastectomy more frequently than women who either had breast-conserving surgery or no history of breast cancer. In multivariate analysis, only positive BRCA mutation carrier status was associated with having had prophylactic surgery. In addition, breast cancer history was significantly associated with prophylactic mastectomy. CONCLUSIONS Women who were BRCA carriers, women who had a history of breast cancer, DCIS, or breast biopsy, or had a family history of ovarian cancer were more likely to have undergone surgery for cancer risk reduction. Women with ovarian cancer or advanced breast cancer were more likely to have undergone surveillance.

Abstract
INTRODUCTION The optimal clinical management of breast cancer (BC) arising in BRCA1/2 mutations carriers is a difficult issue complicated by the risk of subsequent malignancies and by the potential differences in response to local and systemic therapies. AIM Systematically review the difference in outcome after breast conservation therapy (BCT) and uni-or bilateral mastectomy in BRCA1/2 related BC. MATERIAL AND METHODS We selected 20 studies, for which we evaluated the methodology, the characteristics of the populations, biases, confounding risk factors and outcomes. RESULTS All studies are retrospective, entailed by numerous biases. They varied with respect to patients' number, selection, and confounding factors. Hereditary BC patients carried an increased risk of ipsilateral recurrence in 5/17 studies, a worse survival in 4/14, an increased risk of contralateral BC in 14/16. CONCLUSION Except for contralateral risk, the presence of a BRCA mutation does not seem to offer additional prognostic information. Large prospective trials, stratified for risk reduction strategies are warranted.

Abstract
This study prospectively evaluated the utilization of cancer risk management strategies in a multi-institutional cohort of BRCA1 and BRCA2 mutation carriers using a self-report questionnaire. Of 142 unaffected female mutation carriers, 70 (49%) had elected to receive their mutation result. Of those who knew their mutation result, 11% underwent bilateral mastectomy (BM), 29% had bilateral oophorectomy (BO), 78% performed regular breast self-examination (BSE), and 80%, 89%, 67%, and 0% had at least annual clinical breast examination (CBE), mammography, transvaginal ultrasound (TVU), and CA125, respectively. A further 20%, 7%, 0%, 21%, and 75%, respectively, reported never having had these tests. For women who elected not to receive their mutation result, 0% underwent BM, 6% underwent BO, and 77%, 42%, 56%, 7%, and 0% had regular BSE, CBE, mammography, TVU, and CA125, respectively. Only one woman used chemoprevention outside a clinical trial. Uptake of prophylactic surgery and screening was associated with knowing one's mutation status (for all behaviors except BSE), age (for BO and CBE) and residence (for mammography). In this cohort, the minority of mutation carriers utilized risk-reducing surgery or chemoprevention and a substantial minority were not undergoing regular cancer-screening tests.
