If you have breast cancer, are considering a preventive mastectomy, or are helping a loved one learn about breast cancer treatment, you’ve come to the right place. We want to help you make these very personal choices to get the best outcome possible. This information is meant to guide you through your journey and prepare you for the decisions and choices you and your doctors will make together.
For most women, surgery will be part of treatment. Your options may include a lumpectomy (also called breast-conserving surgery), a mastectomy, or a mastectomy with breast reconstruction. The extent of the cancer, the size of your breasts, and your personal preferences will help determine which of these surgeries is the right choice for you.

A lumpectomy, or breast-conserving surgery, removes the cancer (a lump or tumor) and a small rim of healthy breast tissue around it, called the margin. Doctors may refer to this type of surgery as breast-sparing surgery, wide excision, or partial mastectomy. This may be an outpatient surgery, meaning that you don’t have to stay in the hospital overnight unless you have other severe health problems. For most women, a lumpectomy must be followed by radiation to get rid of any remaining cancer cells, lowering the risk that the cancer will return.
Mastectomy is the removal of the entire breast to treat cancer. Doctors may remove one breast or both. When both breasts are removed, doctors refer to it as a bilateral mastectomy. This surgery usually includes the removal of the nipple and the areola (the dark skin around the nipple). The chest (pectoral) muscles under the breast are left intact unless the cancer is near or touching the muscles. If that happens, a small area of muscle may be removed. Types of mastectomy include:Back to top
With early-stage breast cancer, you may be offered a choice between a mastectomy or a lumpectomy followed by radiation therapy. In some women whose cancer cells are scattered throughout the breast or who can’t receive radiation, a mastectomy is medically necessary even though the cancer is early and favorable. While many women opt for lumpectomy, some prefer mastectomy. Discuss the pros and cons of both options with your doctor. It’s helpful to bring a list of the questions and concerns that you’d like to discuss during your appointment to make sure that you get all of the information you need to make the decision that feels best for you.
If you need help thinking of questions to ask your surgeon, here are a few to get you started.Back to top
Although breast cancer treatment usually starts with surgery, there are some situations in which your doctor may recommend chemotherapy first. For example, if you have a large tumor and small breasts, chemotherapy may shrink the tumor enough to make a lumpectomy possible. Having chemotherapy as the first treatment for breast cancer may destroy cancer in the lymph nodes, which may help some women avoid having their lymph nodes removed. For women with some types of advanced breast cancer such as inflammatory cancer, having chemotherapy as the first step in treatment is standard to be sure all the cancer cells can be removed surgically. In studies involving thousands of women, this has been shown to be just as safe as having surgery first.Back to top
You may choose to have breast reconstruction surgery after a mastectomy to rebuild the breast so that it looks similar to the way it did before the surgery. Many times this can be done at the same time as your breast cancer surgery. But it is also possible afterward, even years later. There are many options for reconstruction. After lumpectomy, doctors can enhance the appearance of the breast using fat injections to plump up any dimpled areas where tissue has been removed. They can also perform a breast lift or breast reduction or do plastic surgery on the other breast to create a closely matched pair. After mastectomy, methods of rebuilding the breast include breast implant surgery and using tissue from another part of your body to create a new breast.Back to top
During a lymph node biopsy, a doctor removes lymph nodes to see if cancer cells have spread there. A sentinel node biopsy is the removal of a lymph node or nodes under the arm, called the axillary nodes, which are the first nodes to which cancer cells would travel if they were to leave the breast. This is where the fluid, or lymph, from the tumor flows. If cancer cells are traveling in the lymph system, the sentinel node is more likely than the other lymph nodes to contain them.
This procedure is often done during a mastectomy or lumpectomy. To find the sentinel nodes, a special dye, a low dose of radioactivity, or both are injected into the breast. The nodes containing dye or radioactivity are the sentinel nodes, which are then removed and examined under a microscope. If no cancer is found, no other lymph nodes need to be removed, sparing you a bigger operation.Back to top
An axillary lymph node dissection is when doctors remove most or all of the lymph nodes in the armpit. The procedure may be done if cancer is found in the sentinel nodes. The number of lymph nodes in the armpit varies from person to person but is usually between 15 and 30. In women found to have cancer in their lymph nodes before surgery, giving chemotherapy before surgery is a way to reduce the likelihood of needing an axillary dissection.Back to top
Recovery time depends on which surgery you have:
- After a lumpectomy without a sentinel node biopsy, you’re likely to feel well enough to return to work after two or three days. You can usually resume normal physical activities, like going to the gym, after one week.
- After a lumpectomy with a sentinel node biopsy, you may need to take up to a week off from work to recover.
- After a mastectomy without breast reconstruction, recovery takes three to four weeks. Most women experience pain for a few days after surgery, some for longer periods. Feelings of fatigue can last several weeks as your body heals.
- After mastectomy with breast reconstruction, recovery time can range from four weeks after implant surgery to six to eight weeks for women who have tissue flap reconstruction.
Lymphedema is a buildup of fluid in your hand, arm, and, less frequently, breast or chest wall that can cause swelling and sometimes pain. It is more likely to occur if some or all of your underarm (axillary) lymph nodes are removed as part of your cancer surgery, or if these nodes are treated with radiation. Alert your doctor if you have any symptoms of lymphedema, such as arm swelling, redness, or pain. Prompt treatment — which may include compression garments, exercise, and massage — can be extremely helpful. Some patients can also have surgery to improve the lymphatic circulation and decrease symptoms.Back to top
