People with melanoma on their head or neck are nearly twice as likely to die from the disease as those with the skin cancer on their hands or feet, according to a University of North Carolina study of more than 50,000 melanoma cases. The researchers suspect that's partly because doctors and patients are less likely to spot worrisome skin changes when they're hidden under hair.

So examine your body at least several times a year. Use a blow dryer while checking your scalp and mirrors for the back of your neck and other hard-to-see areas. Go to a physician if you spot suspicious blemishes, and have a doctor examine your skin every year or so.
