"So you've adjusted your fun-in-the-sun routine to include slathering yourself in a protective layer of sunscreen.

But wait: New research has put a few chinks in that armor. Some clinical studies suggest sunscreens do not prevent basal-cell carcinoma and may not reduce the risk of developing the rarer, but more deadly, skin cancer melanoma.

Worse yet, the Environmental Working Group, a nonprofit consumer watchdog agency, found in a 2007 study of nearly 1,100 sunscreens that 87 percent either don't adequately protect you from the sun or have ingredients with significant safety concerns.

Short of spending your life in a darkened room like some character in a Tennessee Williams tale, is it possible to enjoy your summer days without fear of cancer or harmful sunscreen ingredients? Sure, if you keep the following tips in mind."  from article
