An intersectional approach was used to understand sex/gender differences in men's health decisions with regard to hereditary breast cancer (BRCA). A sequential explanatory mixed method design was employed consisting of an online survey with a convenience sample of 101 men who tested positive for the breast cancer mutation following up with an in-depth interview with a subsample of 26 males who participated in the survey. The survey results revealed that 70.3% ( n = 45) considered "Family Risk" as the primary reason for getting BRCA tested; 21.9% ( n = 14) considered "Medical Considerations," and 7.8% ( n = 5) considered "Social Support" as their primary reason. Male participants who were 50 years old or younger or who did not have children were more likely to consider medical reasons as the primary reason to get tested. In terms of self-concept, younger men were more stigmatized than their older counterparts; married men felt a greater loss of control with regard to their BRCA-positive mutation diagnosis than single men; and professional men as a whole felt more vulnerable to the negative influences of the disease than those who had already retired. Regression analysis results indicated that negative self-concept was strongly related to sampled males' BRCA involvement 6 months after testing. Applying an intersectional approach to health care, decision-making outcomes among BRCA-positive mutation males provides an important lens for ascertaining the within-sex/gender demographic and psychosocial factors that affect the diversity of men's pretesting and posttesting medical decisions.
