The Impact of a Family History of Breast Cancer on Screening Practices and Attitudes in Low-Income, Rural, African American Women

The relationship between family history of cancer and cancer attitudes & beliefs within the Community Initiative Towards Improving Equity and Health Status (CITIES) cohort

OBJECTIVE

To determine the relationship between family history of cancer with cancer attitudes and beliefs (CABs) and cancer screening knowledge.

METHODS

This study used data collected for the Community Initiative Towards Improving Equity and Health Status (CITIES) project which surveyed Ohioans ages 21-74. In the current analysis, we included data on age, gender, race, marital status, education, income, financial security, health insurance, CABs, knowledge about the correct age to begin cancer screenings, and presence of a first-degree relative with cancer. Multivariable logistic regression was used to examine the association of family history of cancer with CABs and knowledge about the correct age to begin cancer screening.

RESULTS

Participants were predominantly over the age of 41, female, and white. Out of 603 participants, 295 (48.92%) reported not having a first-degree relative with cancer and 308 (51.08%) reported having a first-degree relative with cancer. Overall, 109 (18.08%) participants reported negative CABs, 378 (62.69%) reported moderate CABs, and 116 (19.24%) reported positive CABs. Participants who reported a first-degree relative with cancer were more likely to report positive CABs, but the association was not significant (p = .11). We observed that older, more educated, and married participants were more likely to have positive CABs (all p < 0.05). Family history of cancer was not associated with differences in knowledge about the correct age for beginning colorectal cancer screening (p = .85) and mammography (p = .88).

CONCLUSIONS

Having a first-degree relative with cancer was not found to be associated with CABs or knowledge about cancer screening. However, age and socioeconomic status were associated with more positive CABs and increased knowledge about cancer screening. Future research should focus on standardizing a CABs scale and expanding the generalizability of our findings.

Self-efficacy of the First-degree Relatives of Patients with Breast Cancer in the Prevention of Cancer: Using the Health Belief Model

Breast cancer is the most common type of cancer in women. The best method to fight this disease is early diagnosis. The aim of this study was to investigate the effect of education based on the health belief model on self-efficacy of the first-degree relatives of patients with breast cancer. This randomized clinical trial was conducted in Tehran in 2016 on 80 first-degree relatives of patients with breast cancer. After purposive sampling, the subjects were assigned to interventions and control groups using the randomized block design. The data collection tool was a questionnaire including questions about demographic data, health belief model, and self-efficacy. The educational intervention was held during four 90-min sessions. The questionnaires were completed before and 8 weeks after the intervention in both groups. The data were analyzed using the SPSS16 software. The educational intervention led to a significant increase in susceptibility (d = 1.17, 95%CI 0.69, 1.66), seriousness (d = 1.11, 95%CI 0.62, 1.59), benefits (d = 1.58, 95%CI 1.06, 2.09), and significant decrease in perceived barriers (d = - 0.73, 95%CI 0.27, 1.19) scores in the intervention group. The self-efficacy score in the intervention group was increased from 7.58 to 9.20, which was statistically significant (d = 1.72, 95%CI 1.19, 2.25). However, in the control group, there was no significant difference in self-efficacy score before and after the intervention (p = 0.45). The present study confirmed the effectiveness of the health belief model in promoting self-efficacy of the first-degree relatives of patients with breast cancer. Therefore, it is recommended that this education program is implemented for women, especially the first-degree relatives of patients with breast cancer.

Breast Cancer Knowledge and Screening Practice and Barriers Among Women in Madinah, Saudi Arabia

A breast screening program may help to reduce cancer mortality rates among women. However, the use of the screening program by women in Madinah city is low, and studies examining its practice and barriers of low uptake are sparse. To identify breast cancer knowledge, practice and screening barriers among women attending primary health centers (PHC) in Madinah, Saudi Arabia. A primary health center-based cross-sectional study was performed in Madinah city in 2015. A multistage stratified cluster sample was obtained and included 465 women (15 years and older) from five PHC. Data concerning socio-demographics, knowledge about breast cancer, and practice and barriers of mammography use were collected using a structured questionnaire. The mean age of the studied 465 women was 34.9 ± 12.2 years. Of these women, 27.7 and 38.5 % received mammography and performed breast self-examination, respectively. A high level of poor knowledge about breast cancer was detected in the overall studied women and those who never received a mammography, particularly knowledge related to the risk factors of breast cancer. The most important predictors of the barriers to mammography were incorrect beliefs about mammography and its procedures. A belief that mammography is painful was significantly associated with a 56 % reduction in its use (OR = 0.44; 95 % CI = 0.22-0.88). The high levels of poor knowledge about cancer breast observed in this study reflect the need for greater efforts to increase breast awareness education.

BRCA1, BRCA2 and PALB2 mutations and CHEK2 c.1100delC in different South African ethnic groups diagnosed with premenopausal and/or triple negative breast cancer

Background

Current knowledge of the aetiology of hereditary breast cancer in the four main South African population groups (black, coloured, Indian and white) is limited. Risk assessments in the black, coloured and Indian population groups are challenging because of restricted information regarding the underlying genetic contributions to inherited breast cancer in these populations. We focused this study on premenopausal patients (diagnosed with breast cancer before the age of 50; n = 78) and triple negative breast cancer (TNBC) patients (n = 30) from the four South African ethnic groups. The aim of this study was to determine the frequency and spectrum of germline mutations in BRCA1, BRCA2 and PALB2 and to evaluate the presence of the CHEK2 c.1100delC allele in these patients.

Methods

In total, 108 South African breast cancer patients underwent mutation screening using a Next-Generation Sequencing (NGS) approach in combination with Multiplex Ligation-dependent Probe Amplification (MLPA) to detect large rearrangements in BRCA1 and BRCA2.

Results

In 13 (12 %) patients a deleterious mutation in BRCA1/2 was detected, three of which were novel mutations in black patients. None of the study participants was found to have an unequivocal pathogenic mutation in PALB2. Two (white) patients tested positive for the CHEK2 c.1100delC mutation, however, one of these also carried a deleterious BRCA2 mutation. Additionally, six variants of unknown clinical significance were identified (4 in BRCA2, 2 in PALB2), all in black patients. Within the group of TNBC patients, a higher mutation frequency was obtained (23.3 %; 7/30) than in the group of patients diagnosed before the age of 50 (7.7 %; 6/78).

Conclusion

This study highlights the importance of evaluating germline mutations in major breast cancer genes in all of the South African population groups. This NGS study shows that mutation analysis is warranted in South African patients with triple negative and/or in premenopausal breast cancer.

African American women's perspectives on breast cancer: implications for communicating risk of basal-like breast cancer

African American women suffer a disproportionately high burden of basal-like breast cancer, an aggressive subtype that has no targeted therapy. While epidemiologic research has identified key prevention strategies, little is known about how best to communicate risk to this population. This study explored women's knowledge, beliefs, and attitudes about breast cancer to learn about risk perceptions. Six focus groups were conducted in North Carolina with 57 women (ages 18-49). Age, race (especially perceptions of cancer as a "White disease"), and lack of family history of breast cancer were all shown to contribute to women's perceptions of low breast cancer susceptibility. Perceptions of low risk were also attributed to conflicting risk information from family, media, and health providers. Women had little to no knowledge of breast cancer subtypes, and emphasized that health communications should be personally relevant, culturally appropriate, and convenient. These findings will assist in developing health communication tools that encourage prevention.

Women's knowledge, attitudes and practice about breast cancer screening in the region of Monastir (Tunisia)

Breast cancer remains a worldwide public health problem. In Tunisia, it is considered to be the primary women's cancer and causes high morbidity and mortality. This study aimed to investigate female knowledge, attitudes and practice of breast cancer screening in the region of Monastir (Tunisia). We conducted a descriptive cross-sectional design exploring knowledge, attitudes and practices of women in the region of Monastir on breast cancer screening. The study was conducted in health centres of this region from 1 March 2009 to 30 June 2009. Data were collected via a structured questionnaire containing 15 items on demographic status, knowledge of risk factors and screening methods and attitudes towards the relevance and effectiveness of breast cancer screening. A scoring scheme was used to score women's responses. A total of 900 women agreed to take part in the study. Their mean age was 41.6±12.4 years and 64% did not exceed the primary level of education. According to the constructed scores, 92% of participants had poor knowledge of the specific risk factors for breast cancer and 63.2% had poor knowledge of the screening methods. Proper practice of breast cancer screening was observed in 14.3% of cases. Multiple logistic regression analysis showed that good knowledge of risk factors and screening methods, higher level of education and positive family history of breast cancer were independently correlated with breast cancer screening practice. This study revealed poor knowledge of breast cancer and the screening methods as well as low levels of practice of breast cancer screening among women in the region of Monastir. Results justify educational programs to raise women's adherence to breast cancer screening programs in Tunisia.

Level of awareness of mammography among women attending outpatient clinics in a teaching hospital in Ibadan, South-West Nigeria

Background

Mammography has been used in developed countries with considerable success but very little is known about this imaging modality in low resource settings. This study examined the level of awareness of mammography and determined factors influencing the level of awareness.

Methods

We conducted a hospital based cross sectional study to investigate the level of awareness of mammography among 818 randomly selected women attending the General Outpatient clinics (GOP) of the University College Hospital (UCH), Ibadan, Nigeria. Independent predictors of level of awareness of mammography were identified using multiple logistic regression analysis.

Results

The proportion of women who ever heard of mammography was 5%, and they demonstrated poor knowledge of the procedure. Those with primary or secondary levels of education were about three times less likely to be aware of mammography when compared with those with tertiary level of education (OR = 0.3, 95% CI, 0.12 – 0.73). Also, participation in community breast cancer prevention activities (OR = 3.4, 95% CI, 1.39 – 8.36), and previous clinical breast examination (OR = 2.34, 95% CI, 1.10 – 4.96) independently predicted mammography awareness. Newspapers and magazines appeared to be the most important sources of information about mammography screening.

Conclusion

The level of awareness of mammography is poor among women attending outpatient clinics in the studied population. Interventions promoting awareness of this screening procedure should give particular attention to the illiterate and older women while clinicians performing breast examinations should utilize the opportunity to inform women about the mammography procedure. Promotion of educational articles on breast cancer and its screening methods via media remains vital for the literate.

The impact of family history of breast cancer on knowledge, attitudes, and early detection practices of Mexican women along the Mexico-US border

Rates of breast cancer (BC) have increased in Mexico, with the highest incidence and mortality rates observed in the northern Mexican states. This study aimed to describe the BC knowledge, attitudes and screening practices among Mexican women with and without a family history of BC residing along the Mexico-US border, and identify factors associated with screening behaviors. One hundred and twenty eight Mexican women aged 40 and older completed an interviewer-administered questionnaire on sociodemographic characteristics, knowledge, family history, and screening practices. There were no significant differences between Mexican women with and without a family history. Over 60% of women in both groups had never had a mammogram/breast ultrasound, and more than 50% had never obtained a clinical breast exam. Age, marital status, insurance, and breast cancer knowledge significantly influenced BC screening behaviors among Mexican women. Further research is needed to examine other key factors associated with screening utilization, in effort of improving BC rates.

The meaning of breast cancer risk for African American women

PURPOSE

To describe African American women's experience of being at high risk for breast cancer.

DESIGN

A hermeneutic phenomenological approach was used to guide in-depth interviews and analysis. Methods to ensure trustworthiness and rigor were included.

METHODS

Open interviews were conducted with 20 African American women who were at high risk for breast cancer (family history, personal history, genetic mutation). They were recruited from a cancer risk clinic and community-based settings. Data were transcribed verbatim, and themes were labeled among and between all interviews.

FINDINGS

Five themes were identified: (a) life-changing experience; (b) relationships: fears, support, and concerns; (c) the healthcare experience; (d) raising awareness; and (e) strong faith.

CONCLUSIONS

Young women at high risk for breast cancer have unique emotional and support needs that are shaped by stage in life, relationships with significant others, their faith, and interactions with the healthcare delivery system.

CLINICAL RELEVANCE

Breast cancer does occur in young women. This highlights the need for timely and sensitive approaches to care when young women present with breast health concerns or abnormal breast findings.

"Are you at risk for hereditary breast cancer?": development of a personal risk assessment tool for hereditary breast and ovarian cancer

Identification of risk for the hereditary breast and ovarian cancer syndrome (HBOC) is important, as research has demonstrated the benefits of risk-reducing interventions for women with or at risk for this disorder. Knowledge among women regarding risk factors for hereditary breast cancer and the existence of cancer genetics services appears limited. The goal of this project was to develop a tool to broaden women's awareness regarding their potential risk for HBOC. A formal instructional design process was used to develop a brochure to facilitate recognition of HBOC risk among women attending a no-cost breast and cervical cancer screening clinic. Brochure development was guided by gathering feedback from potential users early and often. The resulting brochure included four parts: (1) a brief description of the impact of hereditary breast cancer risk on one's health; (2) a personal and family history collection table; (3) a series of questions enabling the user to self-assess HBOC risk; (4) a list of resources for women at risk for HBOC. User feedback indicated that the brochure was easy to use. The project demonstrated that women can self-evaluate their risk for HBOC. Future work will evaluate this tool among a broader population of women.

Risk factors for breast cancer in Turkish women: a hospital-based case-control study

The aim of this study was to investigate the association between risk factors and breast cancer in Turkish women. In a hospital-based case-control study in Istanbul, 405 patients with histologically confirmed breast cancer were compared with 1050 controls, who were admitted to different departments of the same hospital. Unadjusted odds ratios (ORs) and 95% confidence intervals (CIs) for each risk factor were obtained from logistic regression analyses. Risk factors for breast cancer were found to be early menarche age (OR 3.87, 95% CI 2.46-6.08), use of alcohol (OR 3.87, 95% CI 1.79-8.37), history of diabetes (OR 3.31, 95% CI 2.36-4.64) or hypertension (OR 3.44, 95% CI 2.07-5.71), oral contraceptive use (OR 1.98, 95% CI 1.38-2.85) and hormone replacement therapy (HRT) use (OR 1.94, 95% CI 1.15-3.29). The findings of the present study indicated that history of diabetes or hypertension, use of alcohol, oral contraceptive and HRT, never having breastfed and delayed age at first birth associated with changing of lifestyle led to an increased risk of breast cancer in Turkish women.

Early initiation of colorectal cancer screening in individuals with affected first-degree relatives

BACKGROUND

Several guidelines recommend initiating colorectal cancer screening at age 40 for individuals with affected first-degree relatives, yet little evidence exists describing how often these individuals receive screening procedures.

OBJECTIVES

To determine the proportion of individuals in whom early initiation of colorectal cancer screening might be indicated and whether screening disparities exist.

DESIGN

Population-based Supplemental Cancer Control Module to the 2000 National Health Interview Survey.

PARTICIPANTS

Respondents, 5,564, aged 40 to 49 years were included within the analysis.

MEASUREMENTS

Patient self-report of sigmoidoscopy, colonoscopy, or fecal occult blood test.

RESULTS

Overall, 279 respondents (5.4%: 95% C.I., 4.7, 6.2) reported having a first-degree relative affected with colorectal cancer. For individuals with a positive family history, 67 whites (27.9%: 95% C.I., 21.1, 34.5) and 3 African American (9.3%: 95% C.I., 1.7, 37.9) had undergone an endoscopic procedure within the previous 10 years (P-value = .03). After adjusting for age, family history, gender, educational level, insurance status, and usual source of care, whites were more likely to be current with early initiation endoscopic screening recommendations than African Americans (OR = 1.38: 95% C.I., 1.01, 1.87). Having an affected first-degree relative with colorectal cancer appeared to have a stronger impact on endoscopic screening for whites (OR = 3.21: 95% C.I., 2.31, 4.46) than for African Americans (OR = 1.05: 95% C.I., 0.15, 7.21).

CONCLUSIONS

White participants with a family history are more likely to have endoscopic procedures beginning before age 50 than African Americans.
