Katie Donnar, 18, shows her scar from where the melanoma was on the calf of her leg in front of a tanning bed like the one she used at her home and at the tanning salons. Donnar was in the sixth grade when she started using tanning beds, and continues to use them by sitting partially clothed just outside the bed while it is running. "It's not as effective as laying in it like I used to, but the doctors say I have to cut back," she said. (Associated Press)
