Malignant melanoma is the worst of all skin cancers. Excessive exposure to the sun and sensitivity to the sun are considered risk factors that have contributed to the rising incidence of melanoma in this country, but sun exposure is probably not the whole story. Researchers are becoming increasingly aware of the profoundly important role that inheritance, or genetic makeup, has to do with the risk of getting cancer. While melanoma may not be totally preventable because of genetic factors, it can be fully treated if diagnosed early. Cancer researchers believe that atypical cells are on a journey toward becoming true cancer cells. Not all atypical cells finish the march. From the point of view of cancer prevention, the trick is to identify those cells or growths that are atypical and remove them before they do become cancerous. Regular total body skin checkups and skin self-exam help. When caught in time, malignant melanoma is, in most cases, curable. Self examination, early diagnosis, and immediate treatment can literally save your life. Learn the ABCD's of melanoma.

Treatment of Melanoma

Once the diagnosis of melanoma has been made it is important to know its Breslow depth. The risk that you will develop serious problems with melanoma is directly related to how deep the melanoma is. Any melanoma that is up to 1 millimeter in depth has an excellent chance for cure. The cure rate following simple excision is in the range of 96 to 99 percent. Because it is not 100 percent, it is important to emphasize the need for regular monitoring and follow-up examination.

In order to determine how to treat a patient with melanoma and to make some predictions about prognosis, we categorize melanoma in stages. When a melanoma is up to 1 millimeter in depth, excision with 1 centimeter margins down below the level of fat is all that is required. This procedure can be performed in the doctor's office under local anesthesia.

When the melanoma is between 1 and 4 millimeters thick it is clas¬sified as intermediate and may require margins of 2 centimeters when definitive treatment by excision is done. If the melanoma is more than 4 millimeters deep, the margin of safety around the melanoma should be 2-4 centimeters, if it is technically feasible. In some cases smaller margins may be acceptable. Individual circumstances can vary, and there are certainly situations where it is necessary to be more aggressive than the thickness of the cancer alone would suggest.
