Abstract A067: Perceptions and experiences of Black women on hereditary breast and ovarian cancer genetic testing

Abstract

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 but evidence suggests that Black women receive genetic testing for HBOC at lower rates than their White counterparts. To understand Black women’s perspectives on HBOC genetic testing and potential factors influencing this decision, we conducted in-depth qualitative interviews with 107 Black women with a personal or family history of breast or ovarian cancer. Participants were recruited via the networks of patient support organizations and sororities as well as at a family medicine safety net clinic in Jacksonville, FL. Participants frequently expressed a lack of awareness about their family cancer history; many cancer patients stated that they only became aware of extensive family history upon their own diagnosis. Lack of family history sharing was attributed to a culture of silence around medical issues and a desire to protect family members from difficult information. However, most participants indicated a strong desire to understand their own risk of HBOC and were interested in genetic testing. Participants with a personal diagnosis were motivated to undergo HBOC genetic testing to reduce the risk for future generations. Clinical experiences with the offer of HBOC genetic testing were variable, with a few expressing that they had to make repeated inquiries from a provider to understand the relevance of the test to their own health. These findings suggest that investigation into alternative clinical modalities to collect family health history may be beneficial to identify Black women who meet NCCN Guidelines for HBOC testing. In contrast to the literature suggesting hesitancy for HBOC genetic testing, many participants perceived genetic results as having a positive impact for their medical decision-making and family's health. The development of patient materials and provider education on cultural and social factors that influence the uptake of HBOC genetic testing is also needed. Citation Format: Kirsten A.
