Reasons for Procedure

A mastectomy is done:

  • To treat breast cancer
  • To prevent breast cancer if you have a family history of the disease and are at very high risk for breast cancer (occasionally done)
  • To treat severe side effects from previous treatment for breast cancer (rarely done)

Possible Complications

Complications are rare, but no procedure is completely free of risk. If you are planning to have a mastectomy, your doctor will review a list of possible complications, which may include:

Some factors that may increase the risk of complications include:

  • Obesity
  • Poor nutrition
  • Smoking
  • Recent or chronic illness
  • Use of certain medicines or dietary supplements

Be sure to discuss these risks with your doctor before the surgery.

What to Expect

Your doctor may do the following:

  • Physical exam
  • 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

Leading up to the surgery:

  • Talk to your doctor about your medicines and supplements. You may be asked to stop taking some medicines up to one week before the procedure like:
    • Aspirin or other anti-inflammatory drugs
    • Blood thinners, such as clopidogrel (Plavix) or warfarin (Coumadin)
  • Arrange for a ride home. Ask someone to help you at home.
  • Eat a light meal the night before the surgery. Do not eat or drink anything after midnight.

General anesthesia will be used in most cases. It will block any pain and keep you asleep through the surgery. It is given through an IV in your hand or arm.

  • If you had cancer and it has spread, chemotherapy and/or radiation may be needed.
  • The drainage tubes may be removed in 1-2 days.
  • Managing pain and nausea—You might require anti-nausea and pain medicines. You may be nauseated for a few hours after surgery and may not be able to eat normally. Therefore, you may continue to receive fluids and sugar through an IV. For several days after surgery, you may need to eat a lighter, blander diet than usual.
  • Preventing blood clots—You may be given special compression stockings to wear after surgery. These help to decrease the possibility of blood clots forming in your legs.
  • Improving lung function—You may be asked to use an incentive spirometer. This is a device that helps you breathe deeply. It is important to breathe deeply and cough frequently to improve lung function after general anesthesia.
