NCT ID NCT04849871
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a single, focused radiation treatment works as well as five treatments for people with low-risk stage 0 or I breast cancer after a lumpectomy. About 134 participants will be randomly assigned to receive either one or five doses of radiation to the tumor area. The goal is to see if the shorter option keeps cancer from coming back, has similar side effects, and improves quality of life.
