Summary

This study looked at 720 women with early-stage breast cancer who had a lumpectomy. They were split into two groups: one got standard daily radiation for several weeks, the other got a shorter course of higher-dose radiation. The goal was to see if the shorter treatment works just as well to prevent the cancer from coming back, with similar side effects.
