About this trial
The purpose of this study is to find out if adding radiation therapy to routine medications for breast cancer helps in reducing and preventing the cancer from getting worse. Patients with a locally advanced breast cancer who cannot, or do not want to, undergo surgery are eligible to participate. Participation in this study does not prevent you from undergoing surgery in the future.
