subcutaneous mastectomy

subcutaneous mastectomy, a surgical procedure in which all of the breast tissue of one or both breasts is removed, leaving the skin, areola, and nipple intact. The adjacent lymph nodes, pectoralis major, and pectoralis minor are not removed. It may be performed on women who are at great risk of development of breast cancer. Reconstruction of the breasts is performed, with the assistance of a plastic surgeon, through the insertion of prostheses to return the normal contour to the breasts.
