Surgery is the most common treatment for breast cancer. Your doctor can explain each type, discuss and compare the benefits and risks, and describe how each will change the way you look:
This is an operation to remove the cancer but not the breast. It's also called breast-conserving surgery. It can be a lumpectomy or a segmental mastectomy (also called a partial mastectomy). Sometimes an excisional biopsy is the only surgery a woman needs because the surgeon removed the whole lump.
This is an operation to remove the entire breast (or as much of the breast tissue as possible). In some cases, a skin-sparing mastectomy may be an option. For this approach, the surgeon removes as little skin as possible.
The surgeon usually removes one or more lymph nodes from under the arm to check for cancer cells. If cancer cells are found in the lymph nodes, other cancer treatments will be needed.
You may choose to have breast reconstruction. This is plastic surgery to rebuild the shape of the breast. It may be done at the same time as the cancer surgery or later. If you're considering breast reconstruction, you may wish to talk with a plastic surgeon before having cancer surgery.
In breast-sparing surgery, the surgeon removes the cancer in the breast and some normal tissue around it. The surgeon may also remove lymph nodes under the arm. The surgeon sometimes removes some of the lining over the chest muscles below the tumor.
In total (simple) mastectomy, the surgeon removes the whole breast. Some lymph nodes under the arm may also be removed.
In modified radical mastectomy, the surgeon removes the whole breast and most or all of the lymph nodes under the arm. Often, the lining over the chest muscles is removed. A small chest muscle also may be taken out to make it easier to remove the lymph nodes.
The time it takes to heal after surgery is different for each woman. Surgery causes pain and tenderness. Medicine can help control the pain. Before surgery, you should discuss the plan for pain relief with your doctor or nurse. After surgery, your doctor can adjust the plan if you need more relief.
Any kind of surgery also carries a risk of infection, bleeding, or other problems. You should tell your health care team right away if you develop any problems.
You may feel off balance if you've had one or both breasts removed. You may feel more off balance if you have large breasts. This imbalance can cause discomfort in your neck and back.
Also, the skin where your breast was removed may feel tight. Your arm and shoulder muscles may feel stiff and weak. These problems usually go away. The doctor, nurse, or physical therapist can suggest exercises to help you regain movement and strength in your arm and shoulder. Exercise can also reduce stiffness and pain. You may be able to begin gentle exercise within days of surgery.
Because nerves may be injured or cut during surgery, you may have numbness and tingling in your chest, underarm, shoulder, and upper arm. These feelings usually go away within a few weeks or months. But for some women, numbness does not go away.
Removing the lymph nodes under the arm slows the flow of lymph fluid. The fluid may build up in your arm and hand and cause swelling. This swelling is called lymphedema. It can develop soon after surgery or months or even years later. You'll always need to protect the arm and hand on the treated side of your body from cuts, burns, or other injuries.
