WASHINGTON (AP) - Shade your kids. Strong new evidence suggests overall sun exposure in childhood, not just burns, is a big key to who later develops deadly skin cancer. The news comes as the government is finishing long-awaited rules to improve sunscreens.
The Food and Drug Administration wants sunscreens to be rated not just for how well they block the ultraviolet-B rays that cause sunburn — today's SPF rankings — but for how well they protect against deeper-penetrating ultraviolet-A rays that are linked to cancer and wrinkles.
The proposed rules are undergoing a final review and should be issued in weeks, FDA policy director Jeff Shuren told The Associated Press. Still, sunscreen bottles won't look different any time soon: The proposal will be followed by a public comment period before going into effect.
