Global Perceptions of Women on Breast Cancer and Barriers to Screening

PURPOSE OF REVIEW

Breast cancer (BC) is a public health dilemma across the globe and a leading cause of mortality for women. Approximately 2.1 million newly diagnosed female BC cases occurred in 2018, comprising nearly 1 in 4 cancer cases among women. When BC is recognized in its early stages, successful treatment results can be achieved. Therefore, screening for BC is of paramount significance and routine screening mammography has been shown to be effective in reducing mortality from BC. Despite being considered a global health issue, national screening programmes are offered only in developed countries and BC is still often diagnosed in advanced stages.

RECENT FINDINGS

Disparities in screening exist not only between different countries but also between local and immigrant populations within a particular country. Low screening is attributed to low public awareness as well as numerous social, psychological, and geographical barriers to screening. This review addresses (a) the differences in BC awareness and screening across the globe, (b) the most important barriers and facilitators to screening, and (c) the potential role of health education programmes to increase BC awareness and promote BC screening programmes with the ultimate goal to achieve earlier stage diagnosis of BC.

Factors that Influence Mammography Use for Breast Cancer Screening among African American Women

OBJECTIVES

The purpose of this study was to assess factors that influence use of mammography screening among African American women, with a focus on social and cultural influences using Andersen's behavioral model (ABM), and to assess the methodological quality of the included studies.

METHODS

A literature review was conducted using PubMed, CINAHL, PSYCINFO, and Web of Science. Search terms included a combination of the following words using Boolean operators: breast cancer screening, mammography, repeat mammography, and African American. Studies that met the following criteria were included in the review: 1) examined factors associated with mammography screening, 2) included African American women as a majority, 3) published in a peer-reviewed English language journal between 2005 and 2017, and 4) conducted in the United States. Literature reviews, commentaries and non-research studies were excluded. Cited references from identified studies were examined for additional, relevant articles. Associated factors were grouped into predisposing, enabling, and need factor domains of ABM. The reviewed studies were rated using a methodological quality score (MQS) ranging from 0 to 20, with higher scores indicating higher methodological quality.

RESULTS

Twenty-four studies met the inclusion criteria. Fifteen factors that affect breast cancer screening in African American women were identified: predisposing (age, education, knowledge, beliefs, mistrust, religiosity, fears and fatalism), enabling (health insurance, access to care, income, health utilization), and need (physician recommendation, family/personal history, pain/discomfort, family responsibilities) factors. The most common factor was insurance status, although cultural issues (e.g., mistrust) were evident. Most of the identified factors are modifiable. The mean MQS was 12.2, indicating that the studies were slightly above average in quality.

CONCLUSIONS

Financial and cultural issues were important hindrances to breast cancer screening in African American women. These findings highlight the importance of affordable health care for preventive health services as well as the relevance of culturally embedded issues to health, while the MQS accentuates the need for more rigorous research articles. Breast cancer screening interventions in this population should attend to barriers identified in this review.

Making Breast Cancer (Black) History: Results of a Church-Based Primary Prevention Study

Breast cancer rates for African American women are lower than that of their White peers, yet their mortality rate is disproportionately higher. This study sought to address the disparity through a community-based primary prevention study targeting African American women in the Black church utilizing the public health model of primary, secondary, and tertiary prevention. The study centered on the meaningful intersection of race, gender, and faith as key factors in increasing breast health knowledge and breast cancer risk factors. The results reveal that African American women respond positively to intervention models centered on salient aspects of their identity.

Ethnic density and cancer: A review of the evidence

Accumulating data suggest that factors in the social environment may be associated with cancer-related outcomes. Ethnic density, defined as the proportion of racial/ethnic minority individuals residing in a given geographic area, is 1 of the most frequently studied social environment factors, but studies on ethnic density and cancer have yielded inconsistent findings. Thus, the objective of the current review was to summarize the extant data on ethnic density and cancer-related outcomes (cancer risk, stage at diagnosis, and mortality) with the aim of identifying pathways by which ethnic density may contribute to outcomes across populations. In general, the findings indicated an association between ethnic density and increased risk for cancers of infectious origin (eg, liver, cervical) but lower risk for breast and colorectal cancers, particularly among Hispanic and Asian Americans. Hispanic ethnic density was associated with greater odds of late-stage cancer diagnosis, whereas black ethnic density was associated with greater mortality. In addition, this review highlights several methodological and conceptual issues surrounding the measurement of ethnic neighborhoods and their available resources. Clarifying the role of neighborhood ethnic density is critical to developing a greater understanding of the health risks and benefits accompanying these environments and how they may affect racial and ethnic disparities in cancer-related outcomes.

Cultural and emotional determinants of cervical cancer screening among older Hispanic women

Older adults are at highest risk of cancer and yet have the lowest rates of cancer screening participation. Older minority adults bear the burden of cancer screening disparities leading to late stage cancer diagnoses. This investigation, utilization data from the 2008 wave of the Health and Retirement study examined the cultural and emotional factors thought to influence cervical cancer screening among older Hispanic women. We utilized logistic regression models to conduct the analyses. Findings indicate that the emotional factors were not significant but the cultural factor, time orientation was a significant predictor for older Hispanics' cervical cancer screening behaviors.

Breast care screening for underserved African American women: Community-based participatory approach

Traditional health promotion models often do not take into account the importance of shared cultural backgrounds, beliefs, and experiences unique to underserved African American women when designing community-based cancer screening and prevention programs. Thus, the purpose of this study was the development, implementation, and evaluation of a community-based participatory research (CBPR) program designed to increase breast cancer screening awareness in an underserved African American population by providing culturally appropriate social support and information. The study includes 357 African American women who participated in the program and completed the 6-month follow-up questionnaire. The program consisted of a 45-minute play, using community members and storytelling to honor and incorporate five different cultural experiences (skits) with breast care and cancer. Overall, findings indicate that the educational intervention was effective. In addition, these findings are consistent with the literature that suggests that educational interventions that include knowledge to alleviate concerns, dispel myths, and create awareness can increase breast cancer screening participation rates. Furthermore, these findings confirm the importance of CBPR in health promotion activities in reducing health and cancer disparities.

Validation of the Breast Cancer Screening Beliefs Questionnaire among African Australian women

Background

The Breast Cancer Screening Beliefs Questionnaire (BCSBQ) has been designed as a culturally appropriate instrument for assessing women’s beliefs, knowledge and attitudes to breast cancer and breast cancer screening practices. While it has proved to be a reliable instrument when applied to women of Chinese, Arabic and Korean origin living in Australia, its psychometric properties among women from African backgrounds have not been tested. The aim of this study is to examine the psychometric properties of the BCSBQ among African Australian women.

Methods

The BCSBQ was administered to 284 African Australian women who were recruited from a number of African community organizations and churches. Factor analysis was conducted to study the factor structure. Construct validity was examined using Cuzick’s non-parametric test while Cronbach alpha was used to assess internal consistency reliability.

Results

Exploratory factor analysis results demonstrated that the African-Australian BCSBQ can be conceptualized as a 4-factor model. The third factor, viz. “barriers to mammography”, was split into two separate factors namely, “psychological” and “practical” barriers. The results indicated that the African-Australian BCSBQ had both satisfactory validity and internal consistency. The Cronbach’s alpha of the three subscales ranged between 0.84-0.92. The frequency of breast cancer screening practices (breast awareness, clinical breast-examination and mammography) were significantly associated with attitudes towards general health check-ups and perceived barriers to mammographic screening.

Conclusions

Our study provided evidence to support the psychometric properties of the BCSBQ.in African Australian women. The study moreover demonstrated that the use of the instrument can help health professionals to understand the beliefs, knowledge and attitudes to breast cancer among African Australian women and also the factors that impact on their breast cancer screening practices.

Cancer screening barriers for community-based older Hispanics and Caucasians

Despite advances in screening and early detection, ethnic minority populations, ages 65 and older, are less likely than Caucasians to participate in cancer screening services. Empirical research indicates that older ethnic minorities have cultural values that influence their behaviors. Addressing culturally relevant communication to better understand those values may increase participation in cancer screening. The study reported is a secondary analysis of qualitative data gathered from focus groups. Utilizing an interdisciplinary analytical lens, we compared older Hispanic and Caucasian's cultural values and their screening behaviors. Suggested psychosocial interventions are discussed to assist providers in their ongoing efforts to promote cancer screening.

Personal communication in primary and secondary cancer prevention: evolving discussions, emerging challenges

Over the past several years, the science of cancer communication has been recognized as integral to the dissemination of cancer prevention and control strategies in both the general population as well as higher-risk groups. In this article we draw upon current literature and small group discussion in the 2008 Society for Behavioral Medicine Cancer Special Interest Group Pre-Conference Workshop on Cancer Communication to identify current findings, critical challenges, and future opportunities regarding personal communication of primary and secondary prevention of cancer. We organize our article with six critical questions: (1) What are the most important directions of research in this area? (2) Does personal cancer communication work through rational processes, or are affective and nonrational processes also involved? (3) Are our efforts adequate to reach underserved populations? (4) Are naturalistic communicative contexts given adequate consideration? (5) Has the field been adequately informed by social psychological and communication theories? (6) What are the best outcomes to document communication effectiveness? Our goals are to initiate thought and collaborative efforts among communication, public health, and behavioral science experts, as well as to establish research priorities at the interface of communication and cancer prevention and control sciences.

Variations in meanings of the personal core value "health"

OBJECTIVE

Preventive health behavior patterns and practices are influenced by many factors. Knowledge about a person's core values may improve the ability to predict decisions related to behaviors such as healthy eating.

METHODS

In this cross-case comparison study, we illuminate the meanings ascribed to the core value "health" in relationship to fruit and vegetable intake for colorectal cancer survivors and for persons with no cancer history.

RESULTS

We found that both survivors and non-survivors gave three accounts of how the value "health" influenced having a healthy diet. These were: (1) good health was necessary to fulfill/attain other values; (2) health was a manifestation of God's will; and (3) good health was not possible unless one values responsibility.

CONCLUSION

Understanding a person's core values provides insight about how values may act as motivators for behavior change.

PRACTICE IMPLICATIONS

Practitioners using motivational interviewing techniques should include a values clarification exercise to improve their assessment of how values influence behaviors.
