Stop your worrying — a new study indicates you can keep smearing on sunscreens to prevent skin cancer
Worries about skin cancer should supersede concerns about absorbing sunscreen into the bloodstream.

At least that's the conclusion of a new study reported online today by Dr. Aaron E. Carroll in The New York Times.
Skin cancer, the article says, "is the most common malignancy in the United States, affecting more than three million people each year."
But sunscreens, it asserts, "are a key component of preventing skin damage that can lead to skin cancer."
Carroll, a professor of pediatrics at Indiana University School of Medicine who notes that recommendations against UV exposure "apply to everyone," suggests some folks who want to be extra safe switch to sunscreens that contain zinc oxide and titanium dioxide — inorganic compounds that aren't absorbed into the body but sit on the skin reflecting or absorbing the sun's harmful rays.
But even using sunscreens without those two components are unlikely to put you in peril.
The Federal Drug Administration (FDA) study, published in JAMA, tested 24 healthy people. It found that continued use of sunscreens did lead to an accumulation of potentially dangerous chemicals in the body — avobenzone, oxybenzone, octocrlene and ecamsule.
