Can less radiation be just as effective for some breast cancers?
NCT ID NCT07469267
First seen Mar 21, 2026 · Last updated Apr 30, 2026 · Updated 6 times
Summary
This study looks at women with early-stage breast cancer that has spread to 1 or 2 lymph nodes. It compares two types of radiation after surgery: one that treats a larger area of lymph nodes and one that treats only the nearby armpit area. The goal is to see if the smaller radiation area works just as well at preventing the cancer from coming back.
