mastectomy

(măstĕk`təmē), surgical removal of breast tissue, usually done as treatment for breast cancercancer,
in medicine, common term for neoplasms, or tumors, that are malignant. Like benign tumors, malignant tumors do not respond to body mechanisms that limit cell growth.

. There are many types of mastectomy. In general, the farther the cancer has spread, the more tissue is taken. The radical mastectomies of the past (which removed not only the breast, but underlying chest muscle and lymph nodes) have largely been replaced by less drastic, but equally effective procedures. For small tumors, lumpectomy, removing just the tumor and a margin of tissue, may be performed. A partial, or segmental, mastectomy removes the cancer, some breast tissue, the lining over the chest, and usually some lymph nodes from under the arm; total or simple mastectomy removes the whole breast; modified radical mastectomy takes the breast, lining over the chest muscles, and lymph nodes.

Breast reconstruction can be done using the patient's own tissue or breast implantsbreast implant,
saline- or silicone-filled prosthesis used after mastectomy as a part of the breast reconstruction process or used cosmetically to augment small breasts.

. Mammograms and self-conducted breast exams have done much to reduce the need for radical procedures because they have increased early detection of the cancer, allowing it to be treated before it has spread.

Comparative study of surgical margins in oncoplastic surgery and quadrantectomy in breast cancer.
Only the BIS-score was significantly different between women who underwent a chemotherapy intervention (17; quartiles: 9; 22 versus 5; quartiles: 2; 9, P < 0.001, Mann-Whitney U test) and between those who underwent a mastectomy (19; quartiles: 10; 22) versus quadrantectomy (6; quartiles: 3; 11, P < 0.001).
Quadrantectomy versus lumpectomy for small size breast cancer.
Michael Osborne, a surgeon treated the condition by removing a portion of the patient's breast (a quadrantectomy) rather than removing the entire breast.
Compared with standard quadrantectomy or lumpectomy, oncoplastic surgery (ONC) achieves more accurate tumour resection and free resection margins with better cosmesis (23).
While quadrantectomy is too radical and disfiguring for the management of small tumors.
The quadrantectomy consisted of an "en bloc" resection of the parenchyma and pectoralis fascia, with at least a 2 cm macroscopic margin around the tumor.
Pain after quadrantectomy and radiotherapy for early-stage breast cancer: incidence, characteristic and influence on quality of life.
Surgical treatment was administered in 10 patients (38.4%), with wide excisions performed in eight of the patients (8/10, 80%) and quadrantectomy performed in two of the patients (2/10, 20%).
Accessory nipple reconstruction following a central quadrantectomy: a case report.
Usually BCS does not involve resection of skin except for quadrantectomy and a latissimus dorsi flap is ideally suited to reconstruction following quadrantic resection of a tumour in the upper outer quadrant in which the parenchyma together with a narrow radial ellipse of skin has been removed.
One of the studies followed 701 women who had tumors that were no bigger than 2 cm in diameter and were randomized to treatment with a radical mastectomy or a quadrantectomy followed by radiotherapy to the ipsilateral mammary tissue.
