Understanding HER2-positive breast cancer in diverse communities
Her2 status of breast cancer in diverse populations: improving genetic prediction and understanding molecular correlates
This project looks at genetic and tumor features that may explain why HER2-positive breast cancer is more common in Hispanic/Latina, Asian American/Pacific Islander, Indigenous, and other diverse groups.

What this research studies
If you take part, researchers may use your tumor tissue and DNA to look for genetic markers and molecular patterns linked to HER2-positive breast cancer. They will combine tumor profiling, genetic ancestry analysis, and clinical information from people of Hispanic/Latina, Asian American/Pacific Islander, Indigenous, African, and European ancestry. The team will build and improve genetic prediction tools that work better for non-European populations and compare molecular differences across groups. The goal is to make diagnosis and treatment decisions fairer and more accurate for diverse patients.
Who could benefit from this research
Good fit: Ideal candidates are people with breast cancer—especially those from Hispanic/Latina, Asian American/Pacific Islander, Indigenous American, African, or other underrepresented ancestries—who can provide tumor samples or genetic/clinical data.
Not a fit: People without breast cancer or those whose tumors are already known to be HER2-negative should not expect direct personal benefit from this research.
Why it matters
Potential benefit: If successful, this work could help doctors better predict who is likely to have HER2-positive tumors and support fairer use of HER2-targeted treatments across diverse populations.
How similar studies have performed: Prior studies have reported higher proportions of HER2-positive tumors in some non-European groups and related genetic links, but this project expands those findings with broader ancestry-focused molecular and genetic analyses.
