Surgical Procedures for Breast Cancer
by Michelle Badash, MS
Depending on the stage, the location, and the type of tumor, there may be various surgical options available. The goal of surgery is to remove the cancerous tissue and preserve as much healthy breast tissue as possible. Surgery is often one part of a treatment plan that includes chemo- or radiation therapy. In some cases, chemotherapy may be given before surgery to shrink the tumor.
Breast-conserving surgeries, often combined with radiation therapy, are the preferred type of surgeries for eligible women in the early stages of cancer. These surgeries include the removal of the tumor and a small portion of the surrounding healthy tissue. Breast-conserving, also called breast-sparing, surgery options include:
Not all women with stage I or II breast cancer are eligible for these procedures. Conditions that may decrease the benefits of breast-conserving surgeries include:
A mastectomy is the removal of the breast, with or without lymph nodes. There are different types of mastectomies. The best option depends on the extent of the cancer and whether or not breast reconstruction will be done.
Simple (Total) Mastectomy
A simple mastectomy is the most common breast cancer surgery. During this procedure, all breast tissue is removed. A simple mastectomy may be done for women who:
Lymph nodes may be removed and examined for cancer during a simple mastectomy. If they contain cancer, they may be removed in another procedure.
A simple mastectomy may also be an option for women who are at a very high risk for developing breast cancer. Removing one or both breasts before cancer is present is considered a prophylactic or preventive measure. Prophylactic surgery can also be considered for women who have cancer in one breast and have a high risk of cancer in the other breast.
The same amount of tissue is removed as with a simple mastectomy, but the skin over the breast is spared. This can be used when immediate breast reconstruction surgery is planned. Leaving skin for reconstruction is not associated with increased risk of cancer recurrence when compared to a simple mastectomy, but the risks and benefits should be discussed with your doctor when designing a treatment plan.
A variation of this procedure can spare the nipple and areola. The nipple area will be checked for cancer to see if it can be left behind. As an added measure, radiation may be given to the nipple area during or after surgery to reduce the risk of recurrence. This variation may not be an option for all women.
Modified Radical Mastectomy
A modified radical mastectomy may be done if cancer is more invasive or has spread beyond the breast. It involves the removal of the entire breast, the lining of the chest muscle, and possibly some of the muscle in the chest wall. Lymph nodes from under the arm are also removed. Radiation therapy may or may not be required after a modified radical mastectomy, depending on the size of the tumor and whether any cancer was found in the lymph nodes.
This procedure is only considered in rare cases. It is done if the tumor is large and has spread to the muscle in the chest wall under the breast. A radical mastectomy involves removal of the breast, chest wall muscles, lymph nodes under the arm, and some additional fat and skin.
Other Surgical Procedures TOP
Surgery for breast cancer can involve more than just removing the tumor or breast tissue. The lymph nodes are often removed and tested depending on the spread of cancer. Lymph procedures may include:
Women who have lymph nodes removed as part of breast cancer surgery may be at an increased risk for developing lymphedema, a condition caused by blockages of the lymph vessels. Lymph vessels run throughout the body carrying fluid, cells, and other material, but may become blocked when lymph nodes are removed. This can cause a backup of fluid into tissue. Your healthcare team can help you manage lymphedema symptoms.
Women have the option of having breast reconstruction done either at the time of the mastectomy, or some time after the operation. Some women may choose not to have breast reconstruction at all. It will be your decision to determine what you feel most comfortable with.
If you are considering reconstruction, it is best to discuss this option with a plastic surgeon prior to your mastectomy. If you radiation therapy because of the size of the tumor or the presence of any disease in the lymph nodes, make sure your plastic surgeon is aware. Sometimes a waiting period is needed between radiation therapy and breast reconstruction.
