It's odd to find a protein or any bodily object that can help promote a tan and also block cancer development, but a study out of Boston has concluded that exactly that is possible.

The protein promotes a good tan (which fights skin damage by overexposure to the sun) as well as helps protect against skin cancer melanomas. The head author of the study said that "The number one risk factor for melanoma is an inability to tan." How very true that is.

Are you dark or light-skinned? If dark skinned (known as olive skinned, generally), your propensity to develop skin cancer due to melanoma is much lower than light-skinned folks, who tend to need extra protection from the sun.
