If getting a tan is at the top of your summer "to do" list, reconsider before you grab the baby oil and head out to catch some rays.

Sun exposure is the leading cause of skin cancer (such as melanoma) -- the most common type of cancer in the United States. But avoiding the sun altogether is not a very practical or healthy way to live.

The best way to block the harmful ultraviolet rays that burn your skin and can lead to skin cancer is to wear a sunscreen with a 15+ sun protection factor (SPF) and reapply this sunscreen at regular intervals.
