Mastectomy is the surgical removal of the entire breast.
Some women have the option of mastectomy or lumpectomy (also called breast conserving surgery) plus radiation therapy, and choose mastectomy. For other women, mastectomy is the only option.
Learn more about the procedure.
Mastectomy is an option for those who have:
Mastectomy is also used to treat breast cancer that has come back (recurred) after treatment with lumpectomy plus radiation therapy.
Mastectomy is the main treatment for breast cancer in men. This is because men have little breast tissue and most tumors in men occur under the nipple.

Contralateral prophylactic mastectomy is the removal of the opposite (contralateral) healthy breast in a woman diagnosed with breast cancer in one breast. It’s usually done at the same time as breast cancer surgery.
Sometimes, there may be cosmetic reasons to consider surgery to the contralateral breast. For example, some women may choose to have a breast reduction to the contralateral breast to create a more even look with a reconstructed breast.
However, removing the contralateral breast does not lower the risk of dying from the original breast cancer .
The National Comprehensive Cancer Network (NCCN) recommends contralateral prophylactic mastectomy only be considered for women who have a very high risk of breast cancer due to a BRCA1 or BRCA2 (or certain other inherited gene mutations) to try and prevent breast cancer in the contralateral breast .
Women with BRCA1/2 or certain other inherited gene mutations who haven't been diagnosed with breast cancer, may have both breasts removed to try to prevent breast cancer (bilateral prophylactic mastectomy).
There are 2 general types of mastectomy: total (simple) and modified radical.
Your diagnosis guides the type of mastectomy you will have.
Figure 5.2 below shows the types of mastectomy and describes when each is used.
Total (simple) mastectomy
The surgeon removes the entire breast and the lining of the chest muscle, but no other tissue.
For some women, much of the skin of the breast may be left intact for breast reconstruction (called a skin-sparing mastectomy).
In some cases, the nipple may also be left intact (called a nipple-sparing mastectomy).
A sentinel node biopsy may be done, or no lymph nodes may be removed, depending on the breast cancer.
Total (simple) mastectomy may be used to treat:
Total mastectomy is also used for women at high risk who have prophylactic mastectomy.
Sometimes breast reconstruction is done at the same time as a mastectomy.
Modified radical mastectomy
The surgeon removes the entire breast, the lining of the chest muscles and some of the lymph nodes in the underarm area (axillary nodes).
Modified radical mastectomy may be used to treat:
If you are having breast reconstruction at the same time as a mastectomy, the surgeon may be able to use a skin-sparing technique, or possibly a nipple-sparing technique.
A skin-sparing mastectomy removes all of the breast tissue, but saves much of the skin of the breast. The plastic surgeon can use this skin as an envelope to help form the reconstructed breast.
A nipple-sparing mastectomy is a skin-sparing mastectomy that also preserves the nipple and areola.
Some women choose to have breast reconstruction to help restore the look of the breast that was removed.
Reconstruction may be done at the same time as the mastectomy (immediate) or later (delayed). In general, cosmetic results are better with immediate reconstruction.
Discuss your reconstruction options with your plastic surgeon before breast surgery.
Some women choose not to have reconstructive surgery.

Learn about insurance coverage and financial assistance for breast reconstruction.
If you don’t want to have reconstruction, you can get a breast prosthesis. This is a breast form made of silicone gel, foam or other materials that is fitted to your chest.
The form is placed directly on top of your skin or in the pocket of a special bra.
The surgeon will leave the area as flat as possible so the prosthesis can be comfortably fitted to your chest.
Your prosthesis can be properly fitted several weeks after your mastectomy surgery.
Your health care provider can discuss breast prosthesis options with you and help you choose the type that best fits your lifestyle.

Most women who have a mastectomy don’t need radiation therapy.
However, in some cases, radiation therapy is used after mastectomy to treat the chest wall, the lymph nodes in the underarm area (axillary nodes) and the lymph nodes around the collarbone.
If your treatment plan includes chemotherapy, you will have radiation therapy after you finish chemotherapy.
Some women can have a lumpectomy plus radiation therapy instead of a mastectomy.
Learn about deciding between lumpectomy and mastectomy.
Although the exact treatment for breast cancer varies from person to person, guidelines help ensure high-quality care. These guidelines are based on the latest research and agreement among experts.
The National Comprehensive Cancer Network (NCCN) and the American Society of Clinical Oncology (ASCO) are respected organizations that regularly review and update their guidelines.
In addition, the National Cancer Institute (NCI) has treatment overviews.
Talk with your health care providers about which treatment guidelines they use. Since there’s often a lag time between the latest research and guideline updates, most providers prefer to base their treatment on the latest research.
You may not live near the hospital where you will have your surgery.
Sometimes, there are programs that help with local or long-distance transportation and lodging. Some also offer transportation and lodging for a friend or family member going with you.
There are also programs to help you with child care and elder care costs.
