Study: Many Sunscreens May Be Accelerating Cancer

Chart showing relationship between Vitamin A and tumors.Almost half of the 500 most popular sunscreen products may actually increase the speed at which malignant cells develop and spread skin cancer because they contain vitamin A or its derivatives, according to an evaluation of those products released today.

AOL News also has learned through documents and interviews that the Food and Drug Administration has known of the potential danger for as long as a decade without alerting the public, which the FDA denies.

The study was released with Memorial Day weekend approaching. Store shelves throughout the country are already crammed with tubes, jars, bottles and spray cans of sunscreen.

The white goop, creams and ointments might prevent sunburn. But don't count on them to keep the ultraviolet light from destroying your skin cells and causing tumors and lesions, according to researchers at Environmental Working Group.

In their annual report to consumers on sunscreen, they say that only 39 of the 500 products they examined were considered safe and effective to use.

The report cites these problems with bogus sun protection factor (SPF) numbers:

* The use of the hormone-disrupting chemical oxybenzone, which penetrates the skin and enters the bloodstream.

* Overstated claims about performance.

* The lack of needed regulations and oversight by the Food and Drug Administration.

But the most alarming disclosure in this year's report is the finding that vitamin A and its derivatives, retinol and retinyl palmitate, may speed up the cancer that sunscreen is used to prevent.

A dangerous additive

The industry includes vitamin A in its sunscreen formulations because it is an anti-oxidant that slows skin aging.

But the EWG researchers found the initial findings of an FDA study of vitamin A's photocarcinogenic properties, meaning the possibility that it results in cancerous tumors when used on skin exposed to sunlight.

"In that yearlong study, tumors and lesions developed up to 21 percent faster in lab animals coated in a vitamin A-laced cream than animals treated with a vitamin-free cream," the report said.  ...
