Recent work examining attitudes toward breast cancer genetic testing in African American and Latino populations indicates limited knowledge and awareness about testing but a generally receptive view once they are informed; in comparison with whites, African American and Latino populations have relatively more concerns about testing.

For example, in a qualitative focus group study with 51 Latino individuals unselected for risk status, important findings included the fact that participants were highly interested in genetic testing for inherited cancer susceptibility, despite very limited knowledge about genetics. One important barrier involved secrecy or embarrassment about family discussions of cancer and genetics, which could be addressed in intervention strategies.[41] Similarly, a telephone survey of 314 patients, 50% of whom were African American, from an inner-city network of Pittsburgh, Pennsylvania, health centers found that most participants (57%) (both African Americans and whites) felt that genetic testing to evaluate disease risk was a good idea; however, more African Americans than whites thought that genetic testing would lead to racial discrimination (37% vs. 22%, respectively) and that genetics research was unethical and tampered with nature (20% vs. 11%, respectively).[42] Finally, in a study of 222 women in Savannah, Georgia, where most had neither a personal history (70%) nor a family history (60%) of breast cancer, African American women (who comprised 26% of the sample) were less likely to be aware of breast cancer genes and genetic testing. Awareness was also related to higher income, higher education level, and having a family breast cancer history. However, 74% of the entire sample expressed willingness to be tested for breast cancer susceptibility.[43]

In a sample of 146 African American women meeting criteria for BRCA1/2 mutation testing, women born outside the United States reported higher levels of anticipated negative emotional reactions (e.g., fear, hopelessness, and lack of confidence that they could emotionally handle testing). Higher levels of breast cancer–specific distress were associated with anticipated negative emotional reactions, confidentiality concerns, and anticipated guilt regarding the family impact of breast cancer genetic testing.[44] A future orientation (e.g., "I often think about how my actions today will affect my health when I am older") was associated with overall perceived benefits of breast cancer genetic testing in this population (n = 140); however, future orientation was also found to be positively associated with family-related cons of testing, including family guilt and worry regarding the impact of testing on the family.[45]
