Abstract Black women experience significant disparities in morbidity and mortality related to hereditary breast and ovarian cancer (HBOC). Early identification of women with HBOC is essential for proactive screening and timely diagnosis. However, evidence suggests that Black women receive genetic testing for HBOC at lower rates than their White counterparts. We conducted in-depth qualitative interviews with 107 Black women with a personal or family history of breast or ovarian cancer, to understand their perceptions of their familial risk of HBOC and interest in genetic testing. In phase 1 of this study, participants were recruited from the networks of patient support organizations and historically Black sororities representing mostly highly educated and well insured patients. In phase 2, participants were recruited from a family medicine safety net clinic in Jacksonville, FL for socioeconomic diversity. Participants in both cohorts frequently expressed a lack of awareness about their family cancer history and identified many barriers to family disclosure of a cancer diagnosis. These include a culture of silence around medical issues and a belief that personal difficulties should be kept to oneself. Practical and cultural barriers to family history sharing were magnified among those with lower socioeconomic status. Many participants in both cohorts indicated a strong desire to understand their own risk of HBOC. They also expressed interested in genetic testing to proactively mitigate risk to themselves and future generations. Understanding of the potential relevance of HBOC testing to one’s personal health and post-test actionability was variable across both groups, although perceptions of genetic testing were generally favorable. These findings suggest that culturally tailored educational materials and alternative clinical modalities to collect family health history may be beneficial to improve timely identification of Black women who meet NCCN Guidelines for HBOC testing. Specifically, greater attention should be given to addressing barriers that led to underestimation of HBOC risk among patients experiencing disparities driven by adverse social determinants of health.
