Summary

This study tests whether giving an extra dose of radiation (a boost) before breast cancer surgery is safe and helpful. About 103 people with early-stage breast cancer that hasn't spread will receive the boost, then standard radiation and surgery. The goal is to see if this approach reduces side effects and leads to better cosmetic outcomes and tumor control.
