The 2 main options for the surgical management of breast cancer are breast-conserving surgery (BCS) with whole-breast irradiation (WBI) or mastectomy, together with some form of axillary staging. A 20-year follow-up of a randomized clinical trial comparing the 2 options showed no difference in overall survival.1 Local recurrence in the ipsilateral breast was 14.3% in the group receiving BCS with WBI and 39.2% in those who did not receive radiotherapy.1 Breast-conserving surgery with intraoperative radiotherapy has equivalent outcomes in patients with good prognostic features.2
