Simple Mastectomy Health Article

Definition

Simple mastectomy is the surgical removal of one or both breasts. The adjacent lymph nodes and chest muscles are left intact. If a few lymph nodes are removed, the procedure is called an extended simple mastectomy. Breast-sparing techniques may be used to preserve the patient's breast skin and nipple, which is helpful in cosmetic breast reconstruction.

Purpose

Removal of a patient's breast is usually recommended when cancer is present in the breast or as a prophylactic when the patient has severe fibrocystic disease and a family history of breast cancer. The choice of a simple mastectomy may be determined by evaluating the size of the breast, the size of the cancerous mass, where the cancer is located, and whether any cancer cells have spread to adjacent lymph nodes or other parts of the body. If the cancer has not been contained within the breast, it calls for a modified radical mastectomy, which removes the entire breast and all of the adjacent lymph nodes. Only in extreme circumstances is a radical mastectomy, which also removes part of the chest wall, indicated.

A larger tumor usually is an indication of more advanced disease and will require more extensive surgery such as a simple mastectomy. In addition, if a woman has small breasts, the tumor may occupy more area within the contours of the breast, necessitating a simple mastectomy in order to remove all of the cancer.

Very rapidlygrowing tumors usually require the removal of all breast tissue. Cancers that have spread to such adjacent tissues as the chest wall or skin make simple mastectomy a good choice. Similarly, multiple sites of cancer within a breast require that the entire breast be removed. In addition, simple mastectomy is also recommended when cancer recurs in a breast that has already undergone a lumpectomy, which is a less invasive procedure that just removes the tumor and some surrounding tissue without removing the entire breast.

Sometimes, surgeons recommend simple mastectomy for women who are unable to undergo the adjuvant radiation therapy required after a lumpectomy. Radiation treatment is not indicated for pregnant women, those who have had previous therapeutic radiation in the chest area, and patients with collagen vascular diseases such as scleroderma or lupus. In these cases, simple mastectomy is the treatment of choice.

Finally, some women, with family histories of breast cancer and who test positive for a cancer-causing gene, choose to have one or both of their breasts removed as a preventative for future breast cancer. This procedure is highly controversial. Though prophylactic mastectomy reduces the occurrence of breast cancer by 90% in high-risk patients, it is not a foolproof method. There has been some incidence of cancer occurring after both breasts were removed.

Demographics

According to the American Cancer Society in 2003, it was estimated that more than 260,000 new cases of breast cancer in women would occur that year. New cases of breast cancer in men were expected to reach 1,300. Rates of incidence have increased since 1980, due in part to the aging of the population. During the 1990s, breast cancer incidence increased only in women age 50 and over.

For approximately 80% of women, the first indication of cancer is the discovery of a lump in the breast, found either by themselves in a monthly self-exam or by a partner or by a mammogram, a special x ray of the breast that looks for anomalies in the breast. Early detection of breast cancer means that smaller tumors are found that require lessintensive surgery and better treatment outcomes. Simple mastectomy has been the standard treatment of choice for breast cancer for the past 60 years. Newer breast-conserving surgery techniques have been gaining in acceptance since the mid-1980s. For larger hospitals, facilities in urban areas, and health care institutions with a cancer center or high cancer patient volume, these newer techniques are being utilized at a more rapid rate, especially on the East Coast.

Interestingly, though, the National Cancer Institute found in 2003 that American women were 21% more likely to have a mastectomy than their counterparts in the United Kingdom. Though breast-conserving procedures are available and have proven to be viable options, some physicians and women still think breast removal will also remove all of their risk of cancer recurrence. It is clear that treatment options for cancer are highly individual and often emotionally charged.
