NCT00014612

Brief Summary

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells and may be a less invasive treatment and cause fewer side effects than complete axillary lymph node dissection. It is not yet known which treatment is more effective for invasive breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of complete axillary lymph node dissection with that of axillary radiation therapy in treating women who have invasive breast cancer.
