A procedure in which the entire affected breast is removed, called a mastectomy, has been shown to be equally effective in treating breast cancer as lumpectomy, in terms of rates of recurrence and survival. Some women may choose to have a mastectomy...
because they strongly fear a recurrence of breast cancer, and may consider a lumpectomy too risky. Others may feel uncomfortable with a breast that has had a cancer, and would experience more peace of mind with the entire breast removed.
A new technique that may eliminate the need for removing many axillary lymph nodes is being tested. Sentinel lymph node mapping and biopsy is based on the idea that the condition of the first lymph node in the network, which drains the affected area, can predict whether the cancer may have spread to the rest of the nodes. It is thought that if this first, or sentinel, node is cancer-free, then there is no need to look further. Many patients with early-stage breast cancers may be spared the risks and complications of axillary lymph node dissection as the use of this approach continues to increase.

Other Information
Lumpectomy is a common surgical procedure designed to remove a discrete lump, usually a tumor, benign or otherwise, from an affected man or woman's breast. As the tissue removed is generally quite limited and the procedure relatively non-invasive, compared to a mastectomy, a lumpectomy is considered a viable means of "breast conservation" or "breast preservation" surgery with all the attendant physical and emotional advantages of such an approach.
