Mastectomy is a surgical procedure, in which entire breast tissues are removed by the surgeon that are causing concerns in the breast. The surgery contributes in the prevention of breast cancer treatment. Mastectomies may involve the removal of the breast tissue as well as the nipple and breast skin. The skin or nipple may remain after some more new mastectomy procedures. https://healthcheckbox.com/gender-reassignment-surgery/mastectomy-surgery/
