Breast Cancer Screening and Care among Black Sexual Minority Women: A Scoping Review of the Literature from 1990 to 2017

Introduction: Black women are more likely to be diagnosed at later stages of breast cancer compared with White women due to lower frequency of screening and lack of timely follow-up after abnormal screening results. Disparities in breast cancer screening, risk, and mortality are present within both Black women and sexual minority communities; however, there exists limited research concerning breast cancer care among Black sexual minority women. Materials and Methods: This scoping review examines the literature from 1990 to 2017 of the breast cancer care continuum among Black sexual minority women, including behavioral risk factors, screening, treatment, and survivorship. A total of 91 articles were identified through PubMed, PsycINFO, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases. Fifteen articles were selected for data extraction, which met the criteria for including Black/African American women, discussing breast cancer care among both racial and sexual minorities, and being a peer-reviewed article. Results: The 15 articles were primarily within urban contexts, and defined sexual minorities as lesbian or bisexual women. Across all the studies, Black sexual minority women were highly under-represented, and key conclusions are not fully applicable to Black sexual minority women. Sexual minority women had a higher prevalence of breast cancer risk factors (i.e., nulliparity, fewer mammograms, higher alcohol intake, and lower oral contraceptive use). Furthermore, some studies noted homophobia from health providers as potential barriers to engagement in care for sexual minority women. Conclusions: The lack of studies concerning Black sexual minority women in breast cancer care indicates the invisibility of a group that experiences multiple marginalized identities. More research is needed to capture the dynamics of the breast cancer care continuum for Black sexual minority women.
