Spotlight on Skin Cancer
By Lisa Sayoc, M.D.

There are three types of skin cancer, and sun exposure is a common cause. Basal cell carcinoma is the most common skin cancer and can look like a pearly bump or red patch that may bleed and ulcerate. Squamous cell carcinoma is the second most common skin cancer and can appear as a scaly, rough nodule or patch that may ulcerate. Melanoma can appear as a dark-colored or multicolored lesion with irregular borders that may bleed.

The main cause of skin cancer is excessive sun exposure. People who have an increased number of moles or many atypical moles may have an increased chance of developing melanoma. Blistering sunburns as well as a family history of melanoma create a greater risk as well.

Melanoma can occur anywhere on the skin and nails. Pay close attention to moles that change in size, shape, or color as well as spots that are bleeding, tender, or itchy. When looking at your skin, look for the ABCD warning signs:

A = Asymmetry
If you draw a line down the middle of the lesion, are the two sides the same size and shape?

B = Border
Look for moles with ragged, blotchy, or blurred edges.

C = Color
Look for moles that have multiple colors or very dark colors.

D= Diameter
Moles larger than six millimeters, about the same size as a pencil eraser, should be checked by a physician.

To protect your skin, try to limit your time outside when the sun is strongest. Wear protective clothing, and use adequate amounts of sunscreen SPF 15 or higher. Avoid tanning and tanning beds. It is estimated that you will receive about 80 percent of your sun exposure during the first eighteen years of your life, so proper sun safety for infants, children, and teens is vital to preventing skin cancer in later years. See your doctor immediately if you notice any suspicious skin lesion as well as yearly for a professional skin exam.
