What level of alcohol consumption can cause oral cancer?

The Old Statistics: Exposure to 20 alcohol-equivalent-years is associated with oral cancer patients. That means 1 whiskey drink/1 glass wine/6 beers daily for 20 years. Associating factors with a disease & how much contributed to the cancer are not relevant to you. Drink in moderation for its social & health benefits, if you wish & avoid tobacco products. Some oral cancer patients are non-drinkers or light drinkers.

Oral cancer: Many things can do so if you are predisposed or have history of cancer, and your immune system is severely compromised.

Combination: Please forgive the irreverence that others may have shown. In the absence of tobacco use, oral cancer is an uncommon result simply of intemperate drinking; drinker-smokers are the ones at great aocrisk. There are many reasons for keeping your alcohol use under tight control -- the safety of others, avoiding personality deterioration, and remembering the really fun times. Thanks for asking. Cheers.
