What this trial studies

This observational study aims to determine if adding a polygenic risk score (PRS) to standard breast cancer risk assessments can help African American and Hispanic women make more informed decisions regarding breast cancer screening and prevention. Participants will complete surveys and provide blood samples for PRS genotyping, with follow-up surveys conducted over a 10-year period. The study will assess whether the inclusion of genetic risk information influences adherence to screening recommendations and decisions about preventative therapies.

Who should consider this trial

Good fit: Ideal candidates are African American or Hispanic women aged 30 to 75 with specific breast cancer risk factors.

Not a fit: Patients with a calculated low risk for breast cancer or those with a prior history of invasive breast cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could empower minority women with personalized risk information, leading to better screening and prevention strategies for breast cancer.

How similar studies have performed: Other studies have shown promise in using genetic risk scores to enhance breast cancer risk assessments, indicating potential success for this approach.
