While some sunlight is good for health, skin cancer caused by excessive
exposure to sunlight is not among the sun's benefits. Because some types of
skin cancer are easy to cure, the danger posed by too much sunlight is perhaps
not taken seriously enough. It is important to remember that a more serious
form of skin cancer, called melanoma, is also associated with excessive sun
exposure. Melanomas are potentially lethal tumors. Risk of melanoma and other
forms of skin cancer can be significantly reduced by avoiding excessive
exposure to the sun, using sunscreen lotions, and wearing protective clothing
to shield the skin from ultraviolet radiation.
