1 M ELANOMA AND L UNG C ANCER Unit 5: Lifestyle Diseases

2 W HAT IS M ELANOMA ? A tumor of melanin-forming cells, typically a malignant tumor associated with skin cancer.

3 W HAT CAUSES IT ? The main cause of melanoma is too much ultraviolet (UV) radiation reaching the skin. UV rays from the sun and other sources (such as tanning booths) can damage skin cells; causing the cells to grow abnormally. Some people may have a hereditary defect that increases their risk of melanoma.

4 H OW CAN YOU PREVENT IT ? Seek shade: Play it safe in the shade whenever possible and avoid midday sun. UV rays are especially strong between 10 AM and 4 PM. Cover up: Make your own shade with a wide-brimmed hat and long-sleeved shirts and long pants such as blue jeans. Baseball caps and visors shade the face but leave the neck, lower face, and ears exposed. Wear sunglasses: Protect your eyes with UV-blocking sunglasses that have 99% or more UV radiation blocking. Learn not to burn! Just one blistering sunburn when you’re a child or teen more than doubles your risk of developing melanoma (the deadliest form of skin cancer) later in life.
