Protect Yourself Against Sunlight

Skin cancer caused by exposure to sunlight is the most frequently observed type of human cancer. Because skin cancer is often easy to cure, the danger posed by sunlight is perhaps not taken seriously enough. Therefore it is important to know that a more serious form of skin cancer, called melanoma, is also associated with 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 and wearing clothing to shield the skin from ultraviolet radiation. Sunscreen lotions may also protect against some forms of skin cancer, if sun exposure cannot be avoided.
