A mastectomy is surgery to remove a woman's breast. It is usually done to treat breast cancer. Sometimes women at high risk for breast cancer get mastectomies because they want to decrease their risk for breast cancer.
An operation that removes the breast, or as much of the breast as is possible. In a total mastectomy, the surgeon removes the breast and sometimes some lymph nodes under the arm. In a modified radical mastectomy, the breast, most of the lymph nodes, and often some of the lining of the chest muscles are removed. In the rarely used radical mastectomy, the surgeon removes the breast, chest muscles, lymph nodes under the arm, and some additional fat and skin.
The surgical removal of the breast. Lumpectomy: Removal of the lump and a small amount surrounding breast tissue. Simple mastectomy (modified mastectomy): Removal of the entire gland. Radical mastectomy: Removal of the entire breast along with underlying muscle and possibly lymph nodes.
A general term for removal of the breast , usually to remove cancerous tissue. The operation can be done in a hospital or in an outpatient clinic, depending on how extensive it needs to be. It takes from two to three hours, with three to five weeks for full recovery. Drainage shunts are left in the surgical incision for a few days after the operation; these are removed in three to five days if the area is healing normally. After the mastectomy, reconstructive surgery may be performed to restore a more normal appearance. Many patients choose to avoid reconstructive surgery, and wear special undergarments instead. In cases of non- metastatic breast cancer , a lumpectomy, radiation, chemotherapy , or a combination of these treatments may prove a viable alternative to mastectomy. If a lumpectomy is chosen, the surgeon may remove some lymph node tissue from under the arms to make sure cancer has not spread. See the entire definition of Mastectomy
The surgical removal of the breast. Simple mastectomy involves the removal of the entire breast; radical mastectomy involves the removal of the entire breast along with underlying muscle and lymph nodes of the armpit.
Removal of the entire breast. In a simple or total mastectomy surgeons do not cut away any lymph nodes or muscle tissue; in a modified radical mastectomy, surgeons remove the breast and some armpit lymph nodes; in a radical mastectomy (now rarely performed) surgeons remove the breast, armpit lymph nodes, and chest wall muscles under the breast.
Surgical removal of the glandular tissue of the breast/nipple/areolar complex. modified radical mastectomy: Includes removal of the axillary lymph nodes. total/simple mastectomy: Includes removal of breast tissue and the nipple/areola. radical mastectomy: Removal of the breast tissue, nipple/areola, axillary lymph nodes, and pectoral muscle; not commonly done today except for locally advanced breast cancer.
(mas- tek-tuh-me): surgery to remove all or part of the breast and sometimes other tissue. See also modified radical mastectomy, partial or segmental mastectomy, quadrantectomy, simple or total mastectomy, and prophylactic mastectomy.
In medicine, mastectomy is the medical term for the surgical removal of one or both breasts, partially or completely. Mastectomy is usually done to combat breast cancer; in some cases, women believed to be at high risk of breast cancer have the operation prophylactically, that is, to prevent cancer rather than treat it. Alternatively, certain patients can choose to have a wide local excision (also called a lumpectomy), an operation in which a small volume of breast tissue containing the tumor and some surrounding healthy tissue is removed to conserve the breast.
