Radiation Therapy in Treating Women With Locally Recurrent Breast Cancer Previously Treated With Repeat Breast-Preserving Surgery

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy after surgery kill any remaining tumor cells and may be an effective treatment for breast cancer. PURPOSE: This phase II trial is studying how well radiation therapy works in treating women with locally recurrent breast cancer previously treated with repeat breast-conserving surgery.
