The purpose of this study is to determine how circulating tumor DNA (ctDNA), a sign of minimal residual disease (MRD), is detectable after surgery in patients with early HR+/HER2- breast cancer that has spread to 1-3 lymph nodes. Researchers aim to understand if ctDNA detection can identify patients at higher risk of recurrence and guide better treatment decisions. A key aspect is the inclusion of a dedicated cohort of African American/Black women, a group underrepresented in molecular residual disease (MRD) research despite experiencing more aggressive breast cancers. This study will correlate ctDNA results with treatment patterns (radiotherapy, systemic therapy) and outcomes (recurrence-free and overall survival) in both non-African American and African American participants.
