Summary
This study tested giving one or three doses of focused radiation before breast cancer surgery, instead of the usual five to six weeks of radiation after surgery. The goal was to see if this approach can prevent cancer from coming back and spare patients from lengthy treatment. The trial enrolled 139 postmenopausal women with early-stage breast cancer and also looked at safety, immune effects, and breast appearance satisfaction.
