How can I prevent skin cancer?

Keep in mind that protective clothing, such as sun hats and long sleeves, can block out the sun’s harmful rays. Also, lotions that contain sunscreens can protect the skin. Sunscreens are rated in strength according to a sun protection factor (SPF), which ranges from 2 to 30 or higher. Those rated 15 to 30 block most of the sun’s harmful rays.
