Summary

This phase IV trial studies the side effects of intraoperative radiation therapy and how well it works in treating patients with breast cancer undergoing breast-conserving surgery. Delivering radiation one time to the area where the tumor was removed while the patient is still in the operating room may kill any residual tumor cells and may be as effective as standard radiation therapy in patients with early stage breast cancer.
