What Happens During Mastectomy Surgery
A modified radical mastectomy (also known as mastectomy with axillary dissection) procedure can take two to three hours. If there is a reconstruction performed at the same time, the surgery is longer. The surgeon will outline how they expect to go, but mastectomy incisions generally are in the shape of an oval around the nipple, running across the length of the breast. If you are having a skin-sparing mastectomy, the incision will be smaller. This generally includes the nipple, areola, and original biopsy scar.
Once the incision is made, the breast tissue is separated from the overlying skin and from the chest wall muscle underneath. All the breast tissue, which lies between the collarbone and ribs, from the side of the body to the breastbone in the center, is removed. In the case of full, radical mastectomy, some of the chest muscle may be removed as well. If it is part of your surgery plan, an axillary lymph node dissection may also be performed. Immediate reconstruction may be performed at this point, if part of the surgery plan.
Once all removal and replacement work is complete, the surgeon checks the areas for bleeding and inserts surgical drains. These are long tubes that are inserted into your breast area or under the armpit to collect excess fluid that can accumulate in the space where the tumor was. The tubes have plastic bulbs that create suction to help the fluid exit the body. With the drains in place, the surgeon stitches the incision closed. A bandage that wraps closely around your chest covers the entire surgery site.
