[Locoregional treatment of breast cancer: surgery and radiotherapy].

Locoregional control of breast cancer can be achieved with surgery and radiotherapy. Surgery and irradiation is advocated for in situ carcinoma and invasive breast cancer. For T4 lesions, breast cancer locoregional treatment must be performed after neoadjuvant therapy. Locoregional recurrences without distant metastasis need radical surgery with or without neoadjuvant chemotherapy. Locoregional control of breast cancer is a part of the multidisciplinary approach of this disease.
