As with other types of cancer, early detection is critical. Adults should practice skin self-exam regularly. Suspicious spots should be evaluated promptly by a physician. When outdoors, cover as much skin as possible. Use sunscreen with an SPF of 15 or higher.
Some experts recommend taking vitamins and a low fat diet.
It is very important to protect children from the sun because of the possible link between severe sunburns during childhood and increased risk of skin cancer later in life.
