A mastectomy is a surgery that removes breast tissue. There are different mastectomy procedures, including:
- Partial mastectomy or lumpectomy: a tumor and a small margin of surrounding breast tissue is removed
- Simple mastectomy: the entire breast is removed
- Modified radical mastectomy: entire breast and some lymph nodes in the armpit are removed, but chest muscles are left in place
- Radical mastectomy: entire breast, lymph nodes, and chest muscle are removed (rarely done)
Reasons for a Mastectomy
You may have a mastectomy to:
- Treat breast cancer
- Prevent breast cancer if you have a family history of the disease and are at very high risk for breast cancer (occasionally done)
- Treat severe side effects from previous treatment for breast cancer (rarely done)
What to Expect
Prior to the procedure your doctor will perform a physical exam and order tests, including:
- A mammogram: a test that uses low-dose x-rays to make a picture of breast tissue
- Fine needle biopsy of the breast: a thin, hollow needle is used to remove a small tissue sample from the breast
- Blood tests
During the procedure, your surgeon makes an oval-shaped incision in the breast and removes breast tissue, the nipple and areola. To do so, your surgeon cuts the tissue off of the underlying muscle. Your surgeon may need to remove nearby lymph nodes (toward the underarm). A tube drains blood and fluids from the area, and your surgeon closes the area with stitches.
The procedure takes about 1-3 hours and you can expect to stay in the hospital between 1-3 days.
