Breast Cancer Surgery Options

The goal of breast cancer surgery is to remove the tumor and some of the surrounding healthy tissue. Your surgeon will try to save as much of your breast as possible. In some cases, the entire breast must be removed.

It's important to talk with your doctor about each of these operations. That way you can pick the best one for you. Your doctor may recommend a specific operation based on the size, location, or type of breast cancer you have, along with your medical history. 

Types of Breast Cancer Surgery

Breast cancer surgeries differ by the amount of healthy tissue that is removed with the tumor. Some lymph nodes under the armpit are usually removed as part of the operation so they can be checked for cancer cells. This will help your doctor plan your treatment after surgery.

Types of breast cancer surgery include:

Lumpectomy for Breast Cancer


Lumpectomy is also called breast-conserving surgery. The surgeon removes the tumor and a little bit of healthy tissue around it. A second incision under the armpit may be made to remove the lymph nodes.

The goal of a lumpectomy is to leave as much of your healthy breast tissue alone as possible. After the lumpectomy, radiation is usually used to treat any cancer cells that were left behind.

Lumpectomies are best for women who have small, early-stage breast cancers.

Some women shouldn’t get a lumpectomy:

  • Women who have already had radiation for their breast cancer
  • Women who have two or more areas of cancer in the same breast that are too far apart to be removed through one incision
  • Women who have large tumors

If you have a large tumor, sometimes you can get chemotherapy or hormone therapy to shrink it first, and then have a lumpectomy.

Partial or Segmental Mastectomy or Quadrantectomy



In a partial or segmental mastectomy or quadrantectomy, the surgeon removes more breast tissue than with a lumpectomy. The cancerous area and a surrounding area of healthy tissue are removed. Radiation is usually given afterward.
