12 Ways to Protect Your Skin and Prevent Skin Cancer
8. Like children, skin cancers don't always follow rules: The ABCDE rules for melanoma have been well publicized, but not all melanomas conform. One type, amelanotic melanoma, for example, has no brown or black. Another kind, nodular melanoma, is often symmetrical, with fairly regular borders and few colors, says David Polsky, M.D., Ph.D., assistant professor of dermatology and pathology at NYU Medical Center. And invasive melanomas can be smaller than six millimeters — the guideline in the ABCDE rules. The rule for you: Don't dismiss an odd-looking or changing mole because it doesn't resemble the textbook example; show it to a dermatologist.
9. If you're dark skinned, skin cancer is far less common — and far more likely to be fatal: No one's sure why, but among African Americans, Asians, and Hispanics, UV radiation does not play as strong a role in squamous cell carcinoma and melanoma as it does in Caucasians, says Hugh Gloster, M.D., associate professor of dermatology at the University of Cincinnati. He has found that non-Caucasians are far more likely to develop melanoma on the soles of the feet and palms of the hands than on areas that are more heavily sun-exposed like the face and chest. That and the likelihood that doctors aren't looking for skin cancer among dark-skinned patients means the disease may be diagnosed at a later, more dangerous stage, say experts. Since UV rays do play a part in all skin cancers, and basal cell is an equal-opportunity enemy, people of all skin shades need to protect themselves in the sun.
10. You really can get skin cancer where the sun don't shine: The same human papillomavirus (HPV) that's responsible for cervical cancer can cause squamous cell carcinoma of the genitals. While squamous cell growths have at least a 95 percent cure rate overall, those in the genital region tend to be found later, which lowers your odds of survival, says Martin A. Weinstock, M.D., Ph.D., professor of dermatology and community health at Brown University. In a recent review of national mortality records, he found that non-melanoma skin cancers on the genitals, though much rarer than those on other parts of the body, caused about as many deaths. Women were particularly vulnerable; roughly three times as many females as males died of this cancer. Be sure to check the genital area when doing your monthly skin exam, advises Dr. Weinstock. If anything looks suspicious, show a dermatologist.
