FIELD: oncology; may be used in protective and preservation operation. SUBSTANCE: method includes removal of segment of mammary gland and subclavian-axillary-subscapular lymphadenectomy is performed. Four incisions are made to edge the segment to be removed two of which are parallel from areola to retromammary fold or to axillary line. Two other incisions connect the former ones: one along the areol line and the other along the inferior-external contour of mammary gland. After removal of segment, the incision along the inferior-external contour is extended upward towards axillary cavity and downward along retromammary fold. Mammary gland flaps formed in this way are separated - the lower flap is separated through the entire length of skin incision, and the upper flap, up to subclavian region from musculus pectoralis major. The latter is brought out inside, and lymphadenectomy is performed. Skin area round areola is deepitalized. Upper and lower flaps of mammary gland are removed to place of defect and shape of mammary gland is modelled by layer sutures. Areola is fixed in its new position. EFFECT: improved cosmetic effect of radical resection of mammary gland without losses in operation radicality. 4 dwg
