Female breast

A mastectomy is surgery to remove the entire breast. It is usually done to treat breast cancer.

Breast removal surgery; Subcutaneous mastectomy; Total mastectomy; Simple mastectomy; Modified radical mastectomy

You will be given general anesthesia (unconscious and pain-free). The surgeon will make a cut in your breast:

• For a subcutaneous mastectomy, the surgeon removes the entire breast but leaves the nipple and areola (the pigmented circle around the nipple) in place.
• For a total or simple mastectomy, the surgeon cuts breast tissue free from the skin and muscle and removes it. The nipple and the areola are also removed. The surgeon may do a biopsy of lymph nodes in the underarm area to see if the cancer has spread.
• For a modified radical mastectomy, the surgeon removes the entire breast along with some of the lymph nodes underneath the arm.
• For a radical mastectomy, the surgeon removes the overlying skin, all of the lymph nodes underneath the arm, and the chest muscles. This surgery is rarely done.
• The skin is closed with sutures (stitches).

One or two small plastic drains or tubes are usually left in your chest to remove extra fluid from where the breast tissue used to be.

A plastic surgeon may be able to reconstruct the breast (with artificial implants or tissue from your own body) during the same operation. You may also choose to have reconstruction later.

Mastectomy generally takes 2 to 3 hours.

WOMAN DIAGNOSED WITH BREAST CANCER

The most common reason for a mastectomy is breast cancer.

If you are diagnosed with breast cancer, talk to your doctor about your choices:

• Lumpectomy is when only the breast cancer and tissue around the cancer are removed. This is also called breast conservation therapy or partial mastectomy. Part of your breast will be left.
• Mastectomy is when all breast tissue is removed. Mastectomy is a better choice if the area of cancer is too large to remove without deforming the breast.
