Breast cancer knowledge, attitudes, and early detection practices in United States-Mexico border Latinas

Risk perception regarding social determinants of health among women with breast cancer in Iran: a qualitative study

OBJECTIVES

Breast cancer is the most common cancer among women all around the world. Today, in addition to factors including hormones and genetics that are involved in the occurrence of breast cancer, special attention is paid to the role of social and non-medical determinants of health. This study aims to explore the perception of Social Determinants of Health (SDH) in women with breast cancer.

DESIGN

Qualitative study design with a conventional thematic analysis approach.

SETTING

The study was conducted in Tehran, Iran, between December 2021 and February 2023.

PARTICIPANTS

19 women with breast cancer were selected through purposeful and snowball sampling with maximum variation. Sampling continued until data saturation was reached.

PRIMARY AND SECONDARY OUTCOME MEASURES

The study categorised the extracted codes from interviews into three main categories and 12 subcategories related to SDH in women with breast cancer.

RESULTS

The study identified factors such as personal and family health records, health behaviours and lifestyles and medical screening and follow-up as key themes in the perception of SDH among women with breast cancer. The main categories were also categorised into 12 subcategories, 'including family history', 'environmental factors', 'hormonal and medicinal changes', 'metaphysical factors', 'traditional medicine-related factors', 'stress', 'body weight', 'physical activity', 'nutrition', 'smoking and tobacco use', 'screening', 'self-examination' and 'barriers to medical follow-up'. 'Near the telecommunications tower', 'Improper use of supplements', 'Being subjected to the evil eye regularly', 'Eating cold nature foods', 'Breast weight' and 'Being ashamed of the doctor' were some examples of the codes.

CONCLUSIONS

Participants identified a number of environmental, personal and cultural factors as contributing to the disease. Woman's screening behaviours were influenced by factors such as fear of disease and death, disbelief in getting sick and shame, depending on cultural context. The study suggests the need for further research to explore the impact of these factors on screening behaviours and outcomes in different cultural contexts.

Knowledge, attitude, and practice toward ultrasound screening for breast cancer among women

Background

Several obstacles can hinder breast cancer screening. This study aimed to investigate the knowledge, attitude, and practice (KAP) toward ultrasound screening for breast cancer in women.

Methods

This cross-sectional study recruited women who visited the breast specialist clinic of Zhongshan City People's Hospital (a tertiary hospital) between August 2022 and April 2023 through convenience sampling. KAP scores ≥70% were considered adequate.

Results

This study enrolled 501 participants. The mean knowledge, attitude, and practice levels were 8.56 ± 1.81/12 (possible range 0-12, 71.33%), 29.80 ± 2.71 (possible range 8-40, 74.50%), and 32.04 ± 3.09 (possible range 8-40, 80.10%). Senior high school education (vs. junior high school and below, coefficient = 1.531, 95%CI: 1.013-2.312, p = 0.044), bachelor's education and above (vs. junior high school and below, coefficient = 5.315, 95%CI: 3.546-7.966, p < 0.001), housewife or unemployed (vs. employed, coefficient = 0.671, 95%CI: 0.466-0.966, p = 0.032), and a history of breast ultrasound (vs. no, coefficient = 1.466, 95%CI: 1.121-1.917, p = 0.005) were independently and positively associated with knowledge. Knowledge (coefficient = 1.303, 95%CI: 1.100-1.544, p = 0.002) and monthly income >10,000 (vs. <5,000, coefficient = 4.364, 95%CI: 1.738-10.956, p = 0.002) were independently and positively associated with attitude. Only attitude (coefficient = 1.212, 95%CI: 1.096-1.340, p < 0.001) was independently and positively associated with the practice. A structural equation modeling (SEM) analysis was used to estimate causality among KAP dimensions, showing that knowledge directly influenced attitude (β = -1.090, p = 0.015), knowledge did not directly influence practice (β = -0.117, p = 0.681) but had an indirect influence (β = 0.826, p = 0.028), and attitude directly influenced practice (β = -0.757, p = 0.016).

Conclusion

Women in Zhongshan City had good knowledge, favorable attitudes, and active practice toward breast ultrasound screening for breast cancer. Women's characteristics associated with a poorer KAP were identified, allowing for more targeted interventions.

The role of language in mammography orders among low-income Latinas over a 10-year period

INTRODUCTION

Latinas in the United States have higher mortality from breast cancer, but longitudinal studies of mammography ordering (a crucial initial step towards screening) in primary care are lacking.

METHODS

We conducted an analysis of mammography order rates in Latinas (by language preference) and non-Latina white women (N = 181,755) over a > 10 year period in a multi-state network of community health centers (CHCs). We evaluated two outcomes (ever having a mammogram order and annual rate of mammography orders) using generalized estimating equation modeling.

RESULTS

Approximately one-third of all patients had ever had a mammogram order. Among those receiving mammogram orders, English-preferring Latinas had lower mammogram order rates than non-Hispanic white women (RR = 0.92, 95% CI = 0.89-0.95). Spanish-preferring Latinas had higher odds of ever having a mammogram ordered than non-Hispanic whites (odds ratio = 2.12, 95% CI = 2.06-2.18) and, if ever ordered, had a higher rate of annual mammogram orders (rate ratio = 1.53, 95% CI = 1.50-1.56).

CONCLUSION

These findings suggest that breast cancer detection barriers in low-income Latinas may not stem from a lack of orders in primary care, but in the subsequent accessibility of receiving ordered services.

The Effect of 4 Weeks Aerobic Exercise Training with Detraining Courses in Various Prevention Phases on BCl-2 and BAX Genes Expression and Proteins

Background

The aim of this study was to investigate the effect of aerobic exercise with detraining in different phases of prevention on BCL2 Associated X (BAX) and B-cell lymphoma 2 (BCl-2) gene expression and proteins.

Methods

For this purpose, 32 female Balb-c mice (18-20 g) were purchased and randomly assigned to primordial prevention (A), primary prevention (B), secondary prevention (C), and control (D). A group performed aerobic exercise for 4 weeks, after 4T1 cells injection detrained for 8 weeks. Group B performed aerobic exercise for 4 weeks immediately after injecting 4T1 cells and then detrained for 4 weeks. In C group, the 4T1 cells were first injected and did not perform any activity for 4 weeks, followed by 4 weeks of aerobic exercise. Forty-eight hours after the last training session and detraining courses, after anesthesia, sacrificing, and tissue removal, were performed. Reverse transcription polymerase chain reaction (RT PCR) was used to measure gene expression and Western blot (WB) was used to measure protein content. One-way Analysis of variance (ANOVA) test was used to analyze data.

Results

The results showed that aerobic exercise in A, B, and C groups compared to D group reduced BCl-2 gene expression and protein and increased BAX gene expression and protein.

Conclusions

Therefore, exercise can cause apoptosis in tumor cells by increasing pre-apoptotic factors and decreasing antiapoptotic factors in tumor cells, and consequently improving the disease status.

Understanding the role of access in Hispanic cancer screening disparities

BACKGROUND

Hispanic populations in the United States experience numerous barriers to care access. It is unclear how cancer screening disparities between Hispanic and non-Hispanic White individuals are explained by access to care, including having a usual source of care and health insurance coverage.

METHODS

A secondary analysis of the 2019 National Health Interview Survey was conducted and included respondents who were sex- and age-eligible for cervical (n = 8316), breast (n = 6025), or colorectal cancer screening (n = 11,313). The proportion of ever screened and up to date for each screening type was compared.  Regression models evaluated whether controlling for reporting a usual source of care and type of health insurance (public, private, none) attenuated disparities between Hispanics and non-Hispanic White individuals.

RESULTS

Hispanic individuals were less likely than non-Hispanic White individuals to be up to date with cervical cancer screening (71.6% vs. 74.6%) and colorectal cancer screening (52.9% vs. 70.3%), but up-to-date screening was similar for breast cancer (78.8% vs. 76.3%). Hispanic individuals (vs. non-Hispanic White) were less likely to have a usual source of care (77.9% vs. 86.0%) and more likely to be uninsured (23.6% vs. 7.1%). In regressions, insurance fully attenuated cervical cancer disparities. Controlling for both usual source of care and insurance type explained approximately half of the colorectal cancer screening disparities (adjusted risk difference: -8.3 [-11.2 to -4.8]).

CONCLUSION

Addressing the high rate of uninsurance among Hispanic individuals could mitigate cancer screening disparities. Future research should build on the relative successes of breast cancer screening and investigate additional barriers for colorectal cancer screening.

PLAIN LANGUAGE SUMMARY

This study uses data from a national survey to compare cancer screening use those who identify as Hispanic with those who identify as non-Hispanic White. Those who identify as Hispanic are much less likely to be up to date with colorectal cancer screening than those who identify as non-Hispanic White, slightly less likely to be up to date on cervical cancer screening, and similarly likely to receive breast cancer screening. Improving insurance coverage is important for health equity, as is further exploring what drives higher use of breast cancer screening and lower use of colorectal cancer screening.

Evaluation of the quality and accuracy of breast cancer knowledge among persian language websites

INTRODUCTION

The internet has become a powerful worldwide information source that revolutionized access to knowledge, especially in the fields of health and medicine (health knowledge). Therefore, providing high-quality, accurate, reliable, and relevant information on dependable websites is a possible way of providing the patient with needed information and, thus, achieving the benefits of informed patients regarding outcomes. This study aimed to evaluate the quality and accuracy of breast cancer knowledge among Persian language websites.

METHODS

Two search engines were searched in the Persian language about breast cancer. The first 30 websites were selected for further evaluation based on the completeness, correctness, transparency, and accessibility of health knowledge. The DISCERN instrument was used to assess the quality of the Persian language websites on this issue.

RESULTS

Among the 30 websites, about 23% of websites provide completely correct information and about 30% provide mostly correct information. Sixty percent of the websites provided author information, and 46% of them had a healthcare professional or expert as the author. Sixty percent of the websites stated the creation date on the pages, while 40% of them did not provide any health knowledge. Scores on accessibility were always easy for most of the websites. Based on the quality rating system of DISCERN, about 60% of the websites were presented as very poor.

CONCLUSION

Website rankings enable healthcare professionals to identify and signpost patients to reliable up-to-date websites to ensure that patients receive high-quality knowledge. This review has provided evidence of inadequate and inaccurate health knowledge about breast cancer on the Persian language websites. This issue requires further investigation to understand the barriers and solutions available to provide reliable information about breast cancer and how this information affects the patient's outcomes.

The effect of video-based multimedia training on knowledge, attitude, and performance in breast self-examination

Background/Objectives

Breast neoplasm is one of the most common cancers in Iranian women due to the late diagnosis. Awareness of breast neoplasm and using Breast Self-Examination (BSE) assist in the early detection and treatment of cancer. This study examined the effectiveness of video-based multimedia training versus face-to-face training in awareness of breast neoplasm and BSE and possible factors affecting their effectiveness.

Methods

This research was a pre-test, a post-test experimental study comparing the knowledge, attitude, and performance of women about BSE across two training intervention groups (face-to-face versus video-based multimedia). The study was conducted at Shiraz University of Medical Sciences (SUMS), and 100 women between 20 to 60 years old were allocated to each intervention group via multi-stage cluster sampling (n:110). Three valid and reliable researcher-made questioners were used. Data were analyzed using SPSS 24 with independent t-test, paired t-test, and ANOVA.

Results

Both video-based multimedia and face-to-face training methods significantly increased the participant's knowledge, attitude, and skills about breast self-examination (P < 0.001). In the sub-categories, the results showed that the face-to-face training improved negligence and forgetfulness in applying BSE (P = 0.03) and correcting or modifying the previous knowledge around the issue (P = 0.02). The effect of the video-based method on participants with university education was more than on non-university (P = 0.04).

Conclusion

Incorporating video-based multimedia training in awareness of breast neoplasm and breast self-examination provides an easy, flexible, and affordable way for detection, particularly considering crisis restrictions. This can be of particular attention in more populated, developing/low-income countries and rural and remote areas to enhance equitable access to training and facilitation diagnosis and treatment if applicable.

Systematic review of women's knowledge, attitude, and practice towards breast cancer

The present study aims to systematically review the women's knowledge, attitude, and practice (KAP) of breast cancer (BC) screening methods to get enough information for policymakers to orient the screening strategies. All English KAP studies on BC screening methods in five databases up to January 2021 were included. The quality of the final articles was assessed using the STROBE checklist. The qualitative synthesis was performed. Out of 5574 retrieved articles, 28 were included. About 64% of the articles were of high quality. Overall, there were poor knowledge, negative attitude, and low practice between women. The educational programs and cultural plans can encourage regular screening. Women's excessive optimism to their BC risk should be eliminated by focusing on the risk of the disease, more.

Diagnostic Value of Nonacid Nucleic Blood Tumor Marker Panels in Early Diagnosing Breast Cancer: A Systematic Review and Network Meta-Analysis

This study is aimed at determining the best nonacid nucleic blood tumor marker panels in terms of sensitivity, specificity, and accuracy in order to detect breast cancer in early stages (I, II, and III) among eligible women for breast cancer screening. PubMed, Web of Science, Embase, Scopus, and Cochrane were systematically reviewed to assess nonacid nucleic blood tumor marker panels’ diagnostic value in women, both healthy and patient (before any anticancer treatment), for detecting breast cancer. A network meta-analysis was carried out using a Bayesian network meta-analysis to estimate combined odd ratio (OR) and 95% CI credible interval for presenting the results. Rankograms plot was drawn to rank the diagnostic value of different panels. Of the 2358 titles initially identified, 9 studies and 8 panels were included in the network meta-analysis. Panels A (MMP-9/TIMP-1) and K (TF1+TF2+TF3) had the highest sensitivity in early stages, as panel A with $\text{OR}=11.61$ and 95% CI (1.49-102.5) demonstrated a better function than mammography. Panels H (CA 15.3 + IL-18) and A (MMP-9/TIMP-1) had the highest specificity in early stages, but no significant difference with mammography. Panels A (MMP-9/TIMP-1) and H (CA 15.3 + IL-18) had the highest accuracy in early stages, as they significantly exhibited a higher function than mammography with $\text{OR}=6.87$ and 95% CI (2.07-31.35) as well as $\text{OR}=3.44$ and 95% CI (1.15-11.07), respectively. Panel A including MMP-9/TIMP-1 in early stages demonstrated a higher diagnostic value for breast cancer than the rest of the panels.

Functional and Molecular Characters of Cancer Stem Cells Through Development to Establishment

Cancer stem cells (CSCs) are small subpopulation sharing similar properties like normal stem such as self-renewal and differentiation potential to direct tumor growth. Last few years, scientists considered CSCs as the cause of phenotypic heterogeneity in diverse cancer types. Also, CSCs contribute to cancer metastasis and recurrence. The cellular and molecular regulators influence on the CSCs' phenotype changing their behaviors in different stages of cancer progression. CSC markers play significance roles in cancer diagnosis and characterization. We delineate the cross-talks between CSCs and the tumor microenvironment that supports their intrinsic properties including survival, stemness, quiescence and their cellular and molecular adaptation. An insight into the markers of CSCs specific to organs is described.

Breast Density Knowledge and Awareness Among Latinas in a Low-Resource Setting

PURPOSE

Latinas in low-resource settings face additional barriers to understanding mammographic breast density (MBD) implications. The authors compared MBD awareness and knowledge in Latinas from a safety-net clinic in Arizona with a national sample.

METHODS

Latinas 40 to 74 years of age were recruited within a safety-net clinic during screening mammography appointments from 2016 to 2019 (AZ cohort) and from a nationally representative online panel in 2017 (NS cohort). Surveys completed in either English or Spanish assessed awareness and knowledge of MBD. Chi-square tests and logistic regression were used for comparisons.

RESULTS

The NS cohort (n = 152) was older, more educated, more likely to have undergone prior mammography, and more likely to prefer English compared with the AZ cohort (n = 1,327) (P ≤ .03 for all) The NS cohort was more likely to be aware of MBD (32.6% versus 20.7%). Of those aware, the NS cohort was more likely to understand MBD's effect on masking (67.8% versus 37.0%) and breast cancer risk (72.2% versus 32.6%) compared with the AZ cohort (P ≤ .001 for all). Adjusting for age, education, screening history, and language, MBD awareness was similar between the two cohorts (adjusted odds ratio [ORadj], 0.95; P = .83), but knowledge of MBD as a masking factor (ORadj, 2.8; P = .03) and risk factor (ORadj, 7.2; P < .001) remained higher in the NS cohort compared with the AZ cohort.

CONCLUSIONS

Differences in MBD awareness, but not knowledge, between Latinas in a low-resource setting compared with a national sample could be explained by age, education, screening history, and language preference, underscoring the need for tailored approaches to MBD education among Latinas.

The utility of serum tumor markers CEA and CA 15-3 for breast cancer prognosis and their association with clinicopathological parameters

BACKGROUND

We aimed to evaluate the association of serum carcinoembryonic antigen (CEA) and cancer antigen 15-3 (CA 15-3) levels with clinicopathological parameters in patients with breast cancer (BC) and their efficiency for the prediction of recurrence.

METHODS

The records of 482 female patients with breast cancer diagnosis followed in Medical Oncology and Radiation Oncology clinics of Kartal Dr. Lutfu Kirdar Education and Research Hospital were evaluated retrospectively.

RESULTS

The median age of the patients was 49. CEA levels were significantly higher in postmenopausal patients (p = 0.022). There was no association between CEA and CA 15-3 levels and nodal involvement (p = 0.689, 0.379; respectively). CEA levels were significantly higher in hormone receptor-positive patients (p = 0.007). HER2 negative patients had significantly higher levels of CEA and CA 15-3 (p = 0.017 and 0.011, respectively). The evaluation of metastatic patients showed that CEA and CA 15-3 levels before metastasis were significantly elevated (p = 0.016 ve 0.008, respectively). There was no relation between the metastasis site and CEA, CA 15-3 levels (p = 0.936, 0.201, respectively). Receiver operating characteristic (ROC) analysis was performed to determine the role of CEA and CA 15-3 levels in the prediction of metastasis, and cut-off values were 1.39 ng/ml and 14.54 U/ml, respectively. Sensitivities of CA 15-3 and CEA levels were 82.1% and 88.3%; specificities were 47.3% and 46.2%, respectively.

CONCLUSIONS

CEA and CA 15-3 are useful as tumor markers for early diagnosis of metastases, and their elevations were associated with unfavorable clinicopathological parameters of breast cancer patients. Since these markers are considered a cheap and accessible way of predicting breast cancer prognosis, there is an increasing interest in the prognostic value of serum levels of tumor markers in recent years. More sensitive cut-off values for each marker are needed to be validated with further studies.

Synthesis and in vitro Evaluation of Tamoxifen-Loaded Gelatin as Effective Nanocomplex in Drug Delivery Systems

Recently, using gelatin nanoparticles as a biocompatible carrier in drug delivery systems is growing up. Drug delivery is one of the most common applications of nanoparticles in cancer treatment in order to optimize the drug efficiency. In this study, gelatin nanoparticles were firstly synthesized and loaded with tamoxifen that subsequently characterized by SEM, TGA and FT-IR analyses. The approximate drug loading efficiency was calculated about 17.43% for tamoxifen-loaded gelatin (TG). Then, the effect of TG on apoptosis induction and cytotoxicity of MCF-7 cell line was evaluated and compared with flow cytometry and MTT assay. The MTT results showed that tamoxifen and TG nanoparticles could inhibit the proliferation of MCF-7 cells in a dose-responsive manner, with an IC[Formula: see text] of IC[Formula: see text] of 200 [Formula: see text]g/mL and 50 [Formula: see text]g/mL after 24[Formula: see text]h and 48[Formula: see text]h, respectively. Moreover, from flow cytometric results, it can be suggested that TG nanoparticles are more potent in inducing apoptosis and cell death through programmed cell death. Actually, TG nanoparticles primarily increased the early apoptotic cells during the 24-h incubation period Our results revealed that tamoxifen-loaded gelatin nanoparticles are more potent than tamoxifen alone. These findings support the use of tamoxifen-loaded gelatin nanoparticles in target-specific therapy for cancer treatment.

Breast cancer, screening and diagnostic tools: All you need to know

Breast cancer is one of the most frequent malignancies among women worldwide. Methods for screening and diagnosis allow health care professionals to provide personalized treatments that improve the outcome and survival. Scientists and physicians are working side-by-side to develop evidence-based guidelines and equipment to detect cancer earlier. However, the lack of comprehensive interdisciplinary information and understanding between biomedical, medical, and technology professionals makes innovation of new screening and diagnosis tools difficult. This critical review gathers, for the first time, information concerning normal breast and cancer biology, established and emerging methods for screening and diagnosis, staging and grading, molecular and genetic biomarkers. Our purpose is to address key interdisciplinary information about these methods for physicians and scientists. Only the multidisciplinary interaction and communication between scientists, health care professionals, technical experts and patients will lead to the development of better detection tools and methods for an improved screening and early diagnosis.

Determinants of screening methods utilization among Iraq/Sulaimani women

PURPOSE

This study aims to find out the participation rate of women in the utilization of screening methods to determine the relationship of sociodemographic health characteristics and breast cancer (BC) awareness with the utilization of screening methods. The authors' study aims to examine the relationship between women's belief and the utilization of screening methods.

DESIGN/METHODOLOGY/APPROACH

A cross-sectional study was conducted in three health centers from December 13, 2016 to June 12, 2017. A questionnaire was constructed for data collection about sociodemographic characteristics, screening awareness and medical and health background variables. Additionally, BC awareness measure and champion health belief model scales were used to measure women's perceptiveness about BC.

FINDINGS

Despite the awareness among 78.9% of women regarding clinical breast examination (CBE) as a screening method, only 9.5% women utilized it for screening. Due to prescription by physicians for diagnosis of BC, 23.6% women had done mammography at least once in their life. Having jobs and a good education significantly influenced the utilization of CBE as a screening method. The logistic regression analysis found that old age, family history of BC, good knowledge about BC, perceived susceptibility, low rate of perceived barriers to mammography and CBE predicted participation in screening.

ORIGINALITY/VALUE

Enhancing knowledge about BC and screening, emphasizing the susceptibility to BC and the benefits of screening will help in better participation. Importance should be given to illiterate and unemployed women.

Association between health literacy and adopting preventive behaviors of breast cancer in Iran

BACKGROUND

Health literacy plays an important role in adopting preventive behaviors. Considering the relatively high prevalence of breast cancer in women, this study aimed to assess the association between health literacy and adopting the preventive behavior of breast cancer in Iran.

METHODS

This was a descriptive, cross-sectional study, in which 375 female students at Imam Khomeini International University in Qazvin in the academic year of 2018-2019 were selected through a stratified random sampling method. Demographic and background questionnaire, the standard questionnaire of Health Literacy for Iranian Adults in addition to another questionnaire for measuring breast cancer preventive behaviors, were used for collecting data. Data were analyzed using SPSS 22 using descriptive statistics and logistic regression.

RESULTS

The mean of the breast cancer preventive behaviors and health literacy were 8.92 ± 1.82 out of 16 and 70.80 ± 12.49 out of 100. Regression results showed that there was a statistically significant association between the adoption of breast cancer preventive behaviors and physical activity (P < 0.001) and health literacy (P < 0.018). Accordingly, the chance for adopting the preventive behaviors in good level among students with rare and without physical activity was 0.105 and 0.100 times, respectively, more than students who had been doing physical activity on a daily basis. Moreover, the same chance among students with adequate and very adequate health literacy was 1.802 and 2.169 times more than students with inadequate health literacy.

CONCLUSION

The results indicated that students with lower levels of health literacy and less physical activity had shown less tendency to adopt preventive behaviors of breast cancer. Therefore, special attention should be paid to health literacy (HL), particularly physical activity, application of health information, and assessment in students when designing educational programs to prevent breast cancer.

The Body in the Mirror: Breast Cancer, Liminality and Borderlands

Breast cancer is the most common cancer among women worldwide, and has a high mortality rate in northern Mexico. Its high rates present one of the principal health challenges of the California-Baja California border region. We employed "entangled" ethnography and interpretative phenomenological methods to explore breast cancer experiences among a group of Mexican immigrant women living on the US side of this border. We explore their trajectory from biographical disruption to biographical renewal. The entangled ethnographic approach includes reflections of the first author's experience as a genetic breast cancer survivor.

Hispanic Men and Women's Knowledge, Beliefs, Perceived Susceptibility, and Barriers to Clinical Breast Examination and Mammography Practices in South Texas Colonias

Breast cancer is the second leading cause of cancer death among women of all ethnicities. Though the disease is not a primary concern within male populations male perceptions and beliefs of breast cancer screening may contribute to a partner's or loved one's decision to engage in regular mammograms or clinical breast examinations. The current study seeks to explore a comparative analysis of breast cancer knowledge, beliefs, susceptibility, and barriers to female breast cancer and breast cancer screening among Hispanic men and women residing in the Colonias of South Texas. Using a multistage systematic sampling design, 2,812 men and women were surveyed from the two South Texas Counties; Maverick and Val Verde. Individuals between the ages of 20 and 75 (n = 2360) were included in the analysis. T-tests and linear regression models were used to examine gender differences in, knowledge, beliefs, susceptibility, and barriers to breast cancer and breast cancer screening. Significant differences were found between males and females across all measures. Regression analysis demonstrates Hispanic women hold more favorable beliefs about breast cancer and early detection, display higher perceived barriers to clinical breast examinations and mammography, and view themselves more susceptible to the development of breast cancer than their male counterparts. Results framed within a cultural context suggest outreach efforts within South Texas Colonias should consider inclusion of male family members in efforts to increase favorable views toward and engagement in regular breast cancer screening.

Change in Breast Cancer Screening Knowledge is Associated With Change in Mammogram Intention in Mexican-Origin Women After an Educational Intervention

Purpose:

To determine the relationship between breast cancer screening knowledge and intent to receive a mammogram within 6 months in a sample of Mexican-origin women living in El Paso, Texas.

Methods:

A total of 489 uninsured Mexican-origin women were assigned to treatment or control and completed surveys at pre- and postintervention. Pre-post associations between breast cancer screening knowledge and intent were tested.

Results:

Participants were on average were 56.7 years of age and spoke primarily Spanish (92.6%). Most of the samples had not had a mammogram in 3 or more years (51.6%) and 14.6% had never had a mammogram. At baseline, the majority intended to be screened for breast cancer within the next 6 months (93.4%). At postintervention, half of the intervention group changed their 6-month intent to be screened for breast cancer from likely to unlikely. Change in intent was associated with a change in knowledge of risk of having a first child by the age of 30 and breast cancer being rare after the age of 70.

Discussion:

Intent to be screened for breast cancer in Mexican-origin women may be influenced by the type of knowledge.

Conclusions:

Change in screening knowledge may influence perceived risk that influences intention to be screened.

Patterns, knowledge, and barriers of mammography use among women in Saudi Arabia

OBJECTIVES

To assess mammography utilization and knowledge, and to determine barriers associated with mammography utilization among Saudi women. Methods: We conducted a cross-sectional survey in 5 main geographic regions of Saudi Arabia from February 2015 to May 2015. The sample comprised women aged ≥40 years. Associations between socio-demographic factors and mammography use were tested using chi-square test. Predictors of mammography use were assessed by logistic regression. Results: A total of 3,245 women were surveyed, with 40% reporting ever having a mammogram. As indicated by the univariable analyses, older age (≥60 years), being single or divorced, having less than 2 children, not completing high school, and having a family history (hx) of breast cancer were significantly associated with never having a mammogram. Participants of older age (odds ratio [OR] 51-60 versus 41-50 = 0.6, 95% CI: 0.5-0.7 and OR less than 60 versus 41-50 = 0.5, 95% CI: 0.3-0.8), and divorced (OR divorced versus married = 0.6, 95% CI: 0.5-0.8] were less likely to have had a mammogram, while participants with no family hx of breast cancer (OR no family hx versus family hx = 1.5, 95%CI: 1.3-1.8)were more likely to have had a mammogram. Conclusion: Mammography utilization and knowledge are low in Saudi Arabia. Increasing the awareness of breast cancer screening through educational programs could help women overcome existing barriers and misconceptions.

Barriers to early presentation of breast cancer among women in Soweto, South Africa

PURPOSE

Reported breast cancer incidence is rising in South Africa, where some women are diagnosed late and have poor outcomes. We studied patient and provider factors associated with clinical stage at diagnosis among women diagnosed at the Chris Hani Baragwanath Academic Hospital in Soweto, Johannesburg in 2015-2016.

METHODS

From face-to-face interviewer-administered questionnaires we compared self-reported socioeconomics, demographics, comorbidities, risk factors, personal and health system barriers, and from patient clinical records, clinical staging, receptor subtype, and tumor grade among 499 consecutive women newly diagnosed with advanced stage (III/IV) breast cancer versus those diagnosed early (stage 0/I/II). Logistic regression models were used to identify factors associated with advanced stage at diagnosis.

RESULTS

Among the women, 243 (49%) were diagnosed at early and 256 (51%) at advanced stages. In the multiple logistic regression adjusted model, completion of high school or beyond (odds ratio (OR) 0.59, and greater breast cancer knowledge and awareness (OR 0.86) were associated with lower stage of breast cancer at presentation. Advanced stage was associated with Luminal B (OR 2.25) and triple-negative subtypes (OR 3.17) compared to luminal A, with delays >3 months from first breast symptoms to accessing the health system (OR 2.79) and with having more than 1 visit within the referral health system (OR 3.19) for 2 visits; OR 2.73 for ≥3 visits).

CONCLUSIONS

Limited patient education, breast cancer knowledge and awareness, and health system inefficiencies were associated with advanced stage at diagnosis. Sustained community and healthcare worker education may down-stage disease and improve cancer outcomes.

Health system barriers and enablers to early access to breast cancer screening, detection, and diagnosis: a global analysis applied to the MENA region

OBJECTIVES

To identify barriers and enablers that impact access to early screening, detection, and diagnosis of breast cancer both globally and more specifically in the Middle East and North Africa (MENA) region (with a specific focus on Egypt, Jordan, Oman, Saudi Arabia, United Arab Emirates [UAE], and Kuwait) with a specific focus on the health system.

STUDY DESIGN

A systematic review of literature.

METHODS

We conducted a systematic reviewing using the PRISMA methodology. We searched PubMed, Global Index Medicus, and EMBASE for studies on 'breast cancer', 'breast neoplasm,' or 'screening, early detection, and early diagnosis' as well as key words related to the following barriers: religion, culture, health literacy, lack of knowledge/awareness/understanding, attitudes, fatalism/fear, shame/embarrassment, and physician gender from January 1, 2000 until September 1, 2016. Two independent reviewers screened both titles and abstracts. The application of inclusion and exclusion criteria yielded a final list of articles. A conceptual framework was used to guide the thematic analysis and examine health system barriers and enablers to breast cancer screening at the broader macro health system level, at the health provider level, and the individual level. The analysis was conducted globally and in the MENA region.

RESULTS

A total of 11,936 references were identified through the initial search strategy, of which 55 were included in the final thematic analysis. The results found the following barriers and enablers to access to breast cancer screening at the health system level, the health provider level, and the individual level: health system structures such as health insurance and care coordination systems, costs, time concerns, provider characteristics including gender of the provider, quality of care issues, medical concerns, and fear. In addition, the following seven barriers and enablers were identified at the health system or provider level as significantly impacting screening for breast cancer: (1) access to insurance, (2) physician recommendation, (3) physician gender, (4) provider characteristics, (5) having a regular provider, (6) fear of the system or procedure, and (7) knowledge of the health system. More specifically, the largest increased odds for having a mammogram was from having insurance, having a physician recommendation, type of provider (mainly gynecologist), and having regular contact with a physician. Clinical breast examinations were increased by having insurance and having regular contact with a physician. The eight studies identified from the MENA region identified barriers to breast cancer screening related to service quality, fear of pain and of cancer itself, female versus male provider, having a physician recommend the screen, cost issues as well as time and convenience of the services.

CONCLUSIONS

There are a number of system changes that can be made to remove barriers to breast cancer screening. Some of these system changes apply directly to MENA countries. A larger health system assessment of a country is warranted to determine which health system changes should be made to most efficiently and effectively improve access to breast cancer screening.

Latinas' Mammography Intention Following a Home-Based Promotores-Led Intervention

Despite increases in mammography rates among Latinas, screening rates remain lower than in non-Latina Whites and Latinas typically present with breast cancer at a later stage. Trained lay community workers (promotores) have been successfully used to increase screening mammography intention in Latinas. Little is known, however, about the potential mechanisms of these interventions, such as increased breast cancer knowledge (knowledge) and social interactions concerning mammography practices (social engagement). This prospective pre-post study examined this gap in the literature by (1) documenting changes in knowledge and social engagement after receipt of a promotores-based intervention; and (2) establishing if post-intervention knowledge and social engagement predicted mammography intention, after adjusting for socio-demographic and lifetime mammography history. There were significant increases in knowledge and social engagement about mammography. Finally, post-intervention social engagement was a significant predictor of mammography intention. Future promotores-based interventions should focus on enhancing social engagement to improve mammography intention and use.

Socioecological determinants of mammography screening in Mexican rural areas

Purpose

– The purpose of this paper is to determine which socioecological factors encourage rural women to participate in mammographies rather than avoiding taking the test.

Design/methodology/approach

– The study mainly uses data from the 2007 Rural Households Evaluation Survey (ENCEL-2007). These crossover data are analyzed using the framework proposed in the Spatial-Interaction Model of Mammography Use (SIMMU), through a three-level logistic regression model to examine the likelihood that a woman will choose to participate in a mammography.

Findings

– At the woman-household level, the completion of the Pap smear and the asset index is the strongest determinant of mammography participation. Obtaining preventive medicine services or being enrolled in the Popular Insurance System prevent women from undergoing screening. At the interpersonal level, the probability of screening use decreases with lower social coverage. At the intermediate level, availability of health centers is negatively related to the use of screening.

Research limitations/implications

– The study fails to take into account the fact that women’s propensity to have a mammography may vary over time relatively to life changes. Moreover, findings were restricted to women ages from 40 to 49 and limited due to the lack of published data or data quality issues.

Practical implications

– The results of this research can give health planners, policymakers and social marketers a platform for how to approach social change and promote the cancer screening health behavior through the marketing mix (price, place, promotion and product) in the design of their programs.

Originality/value

– In addition to be informative and persuasive with people to change their behavior, this paper also seeks to provide a direction for using commercial marketing tools through social marketing to “sell” the health behavior. Due to target population variation, this paper addresses the health behavior change strategy by audience segmentation, regarded as essential to successful health communication campaigns.

Factors influencing breast cancer screening in low-income African Americans in Tennessee

This study examined demographic and lifestyle factors that influenced decisions and obstacles to being screened for breast cancer in low-income African Americans in three urban Tennessee cities. As part of the Meharry Community Networks Program (CNP) needs assessment, a 123-item community survey was administered to assess demographic characteristics, health care access and utilization, and screening practices for various cancers in low-income African Americans. For this study, only African American women 40 years and older (n = 334) were selected from the Meharry CNP community survey database. There were several predictors of breast cancer screening such as marital status and having health insurance (P < .05). Additionally, there were associations between obstacles to screening and geographic region such as transportation and not having enough information about screenings (P < .05). Educational interventions aimed at improving breast cancer knowledge and screening rates should incorporate information about obstacles and predictors to screening.

Breast cancer knowledge, attitude and screening behaviors among Hispanics in South Texas colonias

This study examines breast cancer knowledge, attitudes and screening behaviors of Hispanic women living in the South Texas colonias of Maverick and Val Verde Counties. We used the Health Belief Model to analyze the effects of HBM constructs on clinical breast exam (CBE) and mammogram screening. Using a multistage systematic sampling approach we interviewed women living within these colonias. Logistic regression analysis was used to predict CBE and mammography screening behaviors. The results indicate that knowledge, susceptibility, barriers and source of health information were statistically significant in predicting CBE among these women. In addition, background variables such as marital status and health insurance were also significant in predicting CBE. Findings further indicate that source of health information, barriers, and health insurance significantly predicts mammography screening behaviors. Results suggest that for women living in colonias along the South Texas Border socio-demographic variables play a significant role in CBE and mammography utilization.

Access to care issues adversely affect breast cancer patients in Mexico: oncologists' perspective

Background

Despite recently implemented access to care programs, Mexican breast cancer (BC) mortality rates remain substantially above those in the US. We conducted a survey among Mexican Oncologists to determine whether practice patterns may be responsible for these differences.

Methods

A web-based survey was sent to 851 oncologists across Mexico using the Vanderbilt University REDCap database. Analyses of outcomes are reported using exact and binomial confidence bounds and tests.

Results

138 participants (18.6% of those surveyed) from the National capital and 26 Mexican states, responded. Respondents reported that 58% of newly diagnosed BC patients present with stage III-IV disease; 63% undergo mastectomy, 52% axillary lymph node dissection (ALND) and 48% sentinel lymph node biopsy (SLNB). Chemotherapy is recommended for tumors > 1 cm (89%), positive nodes (86.5%), triple-negative (TN) (80%) and HER2 positive tumors (58%). Trastuzumab is prescribed in 54.3% and 77.5% for HER2 < 1 cm and > 1 cm tumors, respectively. Tamoxifen is indicated for premenopausal hormone receptor (HR) positive tumors in 86.5% of cases and aromatase inhibitors (AI’s) for postmenopausal in 86%. 24% of physicians reported treatment limitations, due to delayed or incomplete pathology reports and delayed or limited access to medications.

Conclusions

Even though access to care programs have been recently applied nationwide, women commonly present with advanced BC, leading to increased rates of mastectomy and ALND. Mexican physicians are dissatisfied with access to appropriate medical care. Our survey detects specific barriers that may impact BC outcomes in Mexico and warrant further investigation.

A systematic review of barriers and facilitators to mammography in Hispanic women

PURPOSE

A systematic review of the research on barriers and facilitators to mammography in Latinas was conducted to determine if the challenges faced by these women are unique to this population.

METHOD

Medline and CINAHL database searches for the years 2005-2013 were included. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were used to guide this review.

RESULTS

Of the 174 articles identified, 18 articles met inclusion criteria. The most consistent findings were that income and education were associated with screening.

CONCLUSIONS

Financial barriers and social characteristics were significant predictors of mammography in these studies, which were composed almost exclusively of low-income Latinas. These findings are similar to those found in other populations of low-income women and therefore are not likely unique to Latinas.

IMPLICATIONS FOR PRACTICE

It is likely that there is little difference between poor Latinas and other populations of poor, non-English-speaking women in barriers and facilitators to mammography.

An integrated view of cultural perceptions of cancer among Arab people in Israel

The aim of this study was to review published studies on the cultural aspects of screening and care of Arab cancer patients living in Israel. The literature published from the beginning of recording, available up to December 2012, was systematically reviewed. Fifteen studies on perceptions of cancer screening and five studies on different aspects of coping with cancer were identified. Non-attendance of screening for early detection of breast or colorectal cancer was reported to be associated with higher personal barriers (the health belief model) and higher cultural and social barriers. Perceptions of cancer risk, causes, outcomes and personal responsibility were widespread from traditional to more modern biomedical views, and sometimes integrated. Among breast cancer patients, effects of a collective and family centred way of life and strong support by one's spouse were evident, followed by a change towards closer spousal relations. Religious coping strategies were the most prevalent among breast cancer patients and were related to better well-being. An integration of traditional and modern perceptions of cancer, attitudes towards screening and coping with cancer were evident. More research is needed in order to advance a culturally competent care of cancer patients and of interventions that encourage screening for the early detection of cancer.

Comparing perceived and test-based knowledge of cancer risk and prevention among Hispanic and African Americans: an example of community participatory research

BACKGROUND

Most theoretical formulations acknowledge that knowledge and awareness of cancer screening and prevention recommendations significantly influence health behaviors. This study compares perceived knowledge of cancer prevention and screening with test-based knowledge in a community sample. We also examine demographic variables and self-reported cancer screening and prevention behaviors as correlates of both knowledge scores, and consider whether cancer related knowledge can be accurately assessed using just a few, simple questions in a short and easy-to-complete survey.

METHODS

We used a community-partnered participatory research approach to develop our study aims and a survey. The study sample was composed of 180 predominantly African American and Hispanic community individuals who participated in a full-day cancer prevention and screening promotion conference in South Los Angeles, California, on July 2011. Participants completed a self-administered survey in English or Spanish at the beginning of the conference.

RESULTS

Our data indicate that perceived and test-based knowledge scores are only moderately correlated. Perceived knowledge score shows a stronger association with demographic characteristics and other cancer related variables than the test-based score. Thirteen out of twenty variables that are examined in our study showed a statistically significant correlation with the perceived knowledge score, however, only four variables demonstrated a statistically significant correlation with the test-based knowledge score.

CONCLUSION

Perceived knowledge of cancer prevention and screening was assessed with fewer items than test-based knowledge. Thus, using this assessment could potentially reduce respondent burden. However, our data demonstrate that perceived and test-based knowledge are separate constructs.
