Attitudes and intentions to undergo genetic testing for breast cancer susceptibility among Latinas living along the US-Mexico border

Background: Genetic testing for breast cancer may facilitate better-informed decisions regarding cancer prevention, risk reduction, more effective early detection, and better determination of risk for family members. Despite these potential benefits, Latinas lack awareness of genetic testing for breast cancer susceptibility. Among women who are tested, less than 4% are Latina. This study explores attitudes and behavioral intentions to undergo genetic testing among average-risk Latinas along the Texas-Mexico border. Methods: This study surveyed 200 low-income Latinas living in Hidalgo, Starr and Cameron counties, a largely Latino region of South Texas. The questionnaire, developed using simplified language with a maximum fifth-grade readability level and pretested before administration, sought demographic information, breast cancer history and risk, health literacy and numeracy, genetic testing knowledge, attitudes and behavioral intentions, and communication preferences. Results: Participants mostly were of Mexican American origin (93%), had high-school education or less (58%) and had a family income of less than $40,000 (63%). Most participants had positive attitudes and strong interest in genetic testing. Physicians were identified as the most-trusted source of information and medical advice. Barriers and enabling factors associated with genetic testing intentions will be assessed and presented once the analysis is complete. Conclusion: The delivery of culturally adapted risk information is needed to increase and ensure Latinas' understanding of breast cancer genetic testing during their decision-making processes. Key Latino values—religiosity, importance of family and the influential role of health care providers in health decisions—should also be considered when designing interventions targeting this specific group.
