Brief Summary

PURPOSE: This phase II trial studied how well radiation therapy works after surgery in treating women with phyllodes tumor of the breast. RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Radiation therapy following surgery may be effective in treating patients with phyllodes tumor of the breast.
