Malignant melanoma is usually signaled by a change in the size, shape, or color of an existing mole, or as a new growth on normal skin. If you notice any unusual changes on any part of your body, have a doctor check it out. Basal cell carcinoma may come in many forms. It often begins as a small, pearly nodule. Squamous cell carsinoma may begin as a red, scaly patch, a group of crusted nodules, or a sore that doesn't heal.
Malignant melanoma is often asymmetrical, with blurred or ragged edges and mottled colors.
If you're concerned about skin cancer, your family physician is a good place to start. He or she should examine your skin at your annual physical, and can refer you to a specialist if necessary. If you notice an unusual growth yourself, consult a plastic surgeon or a dermatologist. Both are skilled at diagnosing and treating skin cancer and other skin growths. A plastic surgeon can surgically remove the growth in a manner that maintains function and offers the most pleasing final appearance- a consideration that may be especially important if the cancer is in a highly visible area.
