FIELD: medicine.

SUBSTANCE: invention relates to medicine, oncology. Method includes carrying out resection of mammary gland and radiotherapy. After performing resection intraoperational radiotherapy (IORT) is carried out on tumor bed in dose 10 Gy. For this purpose field of irradiation is formed, lower wound edges are tightened with ligatures. After that betatron collimator, whose size corresponds to size of resection, is installed into wound. Upper wound edges are fixed to lower part of collimator in such way that skin and adjacent to it subcutaneous cellular tissue do not get into irradiation zone. Irradiation is performed. After that, axillary lymphadenectomy is carried out. Wound is sutured leaving drainage in axillary region. 2-4 weeks after operation remote gamma-therapy (RGT) is carried out with standard fractionation regimen. Number of RGT sessions is determined by formula: N = 12.6(2.4 -X_u ^-0.169), where N is necessary number of RGT sessions; X_u - time interval in days between IORT and RGT.

EFFECT: method reduces number of complications, ensures achievement of cosmetic result due to reduction of risk of fibrosis development.
