Summary
Brief summary (as posted)
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving intraoperative radiation therapy may reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying how well giving radiation therapy during surgery works in treating older women with stage I breast cancer.
