Narrator: This is Science Today. Now that the summer sun is out, it's time to enjoy the great outdoors – just don't forget about protecting your skin. Melanoma, the deadliest form of skin cancer, is on the rise. Dr. Christopher Zachary, a professor and chair of dermatology at the University of California, Irvine, says one in 75 people will get melanoma at some time in their life. That figure used to be one in 200.

Zachary: Why? In part it's related to your genes, but in part it's the sunshine. As parents, we have a responsibility to our children, who get 50% of their lifetime exposure to sun during the childhood years, to keep those children not necessarily out of the sun, but protected from the sun. So, it's very important that we should have our children educated and our parents educated, that sunshine is fine as long as you learn to live with it in a careful manner – wearing appropriate clothing, wearing sunblock with at least sun protection factor of 15 or higher and it should be protecting you against UVB and UVA.
