First seen Mar 21, 2026 · Last updated Jun 09, 2026 · Updated 11 times

Summary

This study tests whether a short course of radiation (1 to 5 days) after lumpectomy is as safe and effective as the standard 6.5-week whole-breast radiation. It includes women aged 40 and older with small breast tumors. The goal is to reduce treatment time while keeping cancer from coming back and maintaining good cosmetic results.
