Summary
This study looks at whether women with a specific type of breast cancer can safely avoid radiation therapy to their lymph nodes. The participants have hormone-sensitive, HER2-negative tumors with 1-3 positive lymph nodes and a low RecurIndex score. Researchers will track if skipping this radiation leads to cancer returning in the same area. The goal is to reduce unnecessary treatment side effects for low-risk patients.
