Shorter radiation after breast surgery shows promise for cancer control

This study tests whether a shorter, more focused radiation treatment (accelerated partial breast irradiation) after breast-conserving surgery can effectively control cancer in the breast and nearby lymph nodes for people with early-stage breast cancer. About 537 participants with low-risk tumors will receive this radiation over a shorter period than standard whole-breast radiation. The goal is to maintain high cancer control while reducing side effects and treatment time.
