(UPI) - A new study raises the possibility that people who enjoy a glass of white wine every day may face a slightly elevated risk of melanoma.

Total alcohol intake was associated with a 14 percent higher risk of melanoma per drink per day, researchers found.

But, when they looked at the type of alcohol consumed, white wine emerged as the potential culprit. Each drink per day of white wine was associated with a 13 percent higher risk of melanoma, the researchers said.

"Per drink" risk was based on 12.8 grams of alcohol -- the median amount of alcohol in a beer, a glass of wine or a shot of spirits.

Beer, red wine and liquor did not significantly affect melanoma risk, the study authors added.

The study does not prove that white wine causes this deadly skin cancer. It merely shows an association, though one worth exploring, the researchers said.
