Sunscreens and Cancer Risks

Sunscreens are supposed to help reduce the risk of skin cancer, not cause it. Right? Well, there's new data indicating that this may not be the case, that retinyl palmitate - a form of vitamin A commonly used in sunscreens - might actually cause cancer.

A Times article reports that recent studies have found a possible correlation between retinyl palmitate and the development of tumors in rats exposed to the chemical.

As alarming as this may seem, remember that these are early studies – done on rats. Much more research needs to be done – and on human skin – before any real conclusions can be made.

Nevertheless, if you’d like to avoid sunscreens using retinyl palmitate, check out the Environment Working Group’s sunscreen guide for a list of alternatives.

Do not toss your sunscreen. Aside from wearing a hat, a long sleeve shirt and pants, sunscreens are the best known tool to help reduce skin cancer risk.
