Alcohol consumption increases your risk for cancers of the mouth, pharynx, larynx, oesophagus, colorectal (for men) and breast. There is further evidence to show a probable link with liver cancer and colorectal cancer in women.
Cancer Care Ontario recommends for cancer prevention to limit alcohol consumption to no more than 1 drink per day for women and 2 drinks per day for men. The increased risk is based on amount of alcohol consumed, not the type: one drink is defined as 12 ounces of beer, 5 ounces of wine or 1.5 ounces of liquor.
