A signal lymph node which accumulates a radiopharmaceutical is detected, then it is removed and an urgent histologic examination is performed. If there is no metastases in the signal lymph node, the breast tissue sector is excised together with the tumor, and if observing the tumor changes in the signaling lymph node, the breast tissue sector is excised together with the tumor and lymphadenectomy. 
     EFFECT: method provides surgical treatment of breast cancer at early stages of tumor process with individualization of lymphadenectomy volume, as well as minimization of irradiation of patient and reduced time of operation due to intraoperative examination of signaling lymph node.
