Water reflects up to 100 percent of UV radiation. Typically, people don't develop any type of skin cancer until after age 50. However, outdoor workers often develop it at an earlier age. Sun damage builds up slowly and quietly. The most common warning sign of skin cancer is a change on the skin, especially a new growth or a sore than doesn't heal. Skin cancers don't all look the same. The cancer may start as a small, smooth, shiny, pale, or waxy lump, or it can appear as a firm red lump. Sometimes, the lump bleeds or develops a crust. Skin cancer also can start as a flat, red spot that is rough, dry or scaly. Both basal and squamous cell cancers are found mainly on areas of the skin that are exposed to the sun — the head, face, neck, hands and arms. However, skin cancer can occur anywhere. Changes to moles also are worrisome. BEST DEFENSE To prevent skin cancer, follow these simple steps from the American Cancer Society. SLIP on a long-sleeved shirt. SLOP on sunscreen with SPF 15+ to 30+ for faii-skinned individuals. Lip balm with sunscreen also is recommended. SLAP on a wide brim hat. Ears, noses and lips are common sites of skin cancer. Prevention of melanoma is obviously the most desirable weapon against the disease. But if a lesion should develop, it is often curable if caught in the early stages. To aid in early recognition of any new or developing lesion, periodic self-examinations are helpful. "Always remember when you're working on the water, you're also working on cancer,"
