Radiation therapy is an essential component of the local management of breast cancer. The overview from the Early Breast Cancer Trialists Collaborative Group (1) indicates that adjuvant radiation therapy after breast-conserving surgery results in statistically significant reductions in the 5-year risk of local recurrence (26% versus 7%), the 15-year breast cancer mortality risk (5.4% reduction), and overall mortality (5.3% reduction). The benefits of radiation therapy are similar for those patients treated after mastectomy, with reductions in local recurrence, breast cancer mortality, and overall mortality. Although the overview clearly shows the benefit of radiation, it also has confirmed the toxicities. Patients who were treated with radiation had increased risk of contralateral breast cancer, lung cancer, and mortality from cardiac disease (rate ratio = 1.27, P<.001). The
