It used to be thought that the more the surgeon cut from a woman’s breast, the more likely she was to survive breast cancer. By the time surgery was over, a woman with a small tumor in one breast would have lost her breast, the chest muscles underneath and a trail of the lymph nodes up to her collarbone. It’s an image that still holds great power for many women who are newly diagnosed, but it’s an erroneous one.
Fortunately, such radical surgery is now rare. Mastectomies, in which the whole breast is removed, are far less invasive and disfiguring than before. And doctors have increasingly recommended that women with early-stage breast cancer undergo a less invasive surgery called a lumpectomy, which involves removing only the “lump,” or tumor, and some surrounding tissue. Long-term studies have shown that for women whose tumors are small and caught early, lumpectomy with radiation is as lifesaving as mastectomy.
The amount of tissue you’ll need to have removed depends on the size and location of the tumor, how aggressive it is, and what options you have in terms of additional therapies. (Almost all breast cancer patients need further treatment after surgery, such as radiation, chemotherapy, hormone therapy, or a combination of these, in order to kill off any cancer cells that remain.) If your tumor is expected to respond well to hormone therapy and radiation, for example, it may be possible to have a portion of the breast removed rather than all of it. Here are the different types of surgery you and your doctor will choose from.
Lumpectomy
If your cancer is caught in stage I or II, meaning that it’s less than 5 centimeters in diameter and hasn’t spread beyond the lymph nodes into the rest of the body, you may be able to have a lumpectomy. In this surgery, usually an outpatient procedure, the cancerous area is removed, along with some surrounding tissue and possibly some lymph nodes. Most patients need six to seven weeks of radiation therapy afterward. Many studies have found that for women whose tumors are 5 cm. or less, a lumpectomy followed by radiation can be as successful in preventing the recurrence of cancer as a mastectomy without radiation. Roughly half of all women with breast cancer opt for lumpectomies.

Segmental Mastectomy
If the size of your tumor makes a simple lumpectomy impossible, another form of breast-conserving surgery may still be an option. A segmental mastectomy sometimes called a partial mastectomy — involves the removal of about a fourth of the breast, including the tumor, the lining over the chest muscles below the tumor, some surrounding tissue, and some nearby lymph nodes. Six to seven weeks of radiation therapy will probably follow.
Mastectomy
If your tumor is large or aggressive, you may need a mastectomy, in which your whole breast is removed. This might also be a good choice for you if you’re looking to avoid radiation treatment, want to minimize the chance that cancer will recur, or plan to have your breast reconstructed. A simple mastectomy removes only the breast tissue, but most women end up having a modified radical mastectomy. In this procedure, the surgeon also removes many of the nearby lymph nodes, the lining over the chest muscles, and sometimes part of the chest muscles themselves. You’ll be in the hospital for a day or two afterward. Breast reconstruction, if you choose it, can often be done at the same time or you can wait till a later date. A radical mastectomy requires the removal of all the nearby lymph nodes and chest muscles, but it’s rarely performed these days unless a cancer has spread into the muscles.

Why might I need to have lymph nodes removed?
Many women who undergo surgery for breast cancer need to have some or all of their axillary (underarm) lymph nodes removed to determine how far their cancer has spread and what other therapies may be necessary. Lymph nodes are small, bean-shaped glands. They contain lymph, a colorless fluid that circulates throughout your body like blood, carrying toxins away from your tissues. If cancer gets into the lymph nodes, it can spread more easily throughout the body. Typically, several nodes are removed for examination during a biopsy. If cancer is found in one, the surrounding nodes are removed as a precautionary measure.
An increasingly popular way to spare a woman unnecessary removal of lymph nodes is called sentinel lymph node mapping. The doctor injects a radioactive dye into your breast, which takes the same path to the lymph nodes that cancer cells would take. The surgeon can then tell which is the sentinel node, the one that serves as the gatekeeper for all the others, and remove it for biopsy. If it’s cancer-free, chances are good that you won’t need to have other lymph nodes removed.
