Studies around the world have shown that drinking alcohol regularly increases the risk of getting mouth, voice box, and throat cancers. Consuming around 50 grams of alcohol or more daily can double or triple the risk for these cancers compared to the risk of non-drinkers. More than 100 studies have found an increased risk of breast cancer with increased alcohol intake. There is also evidence that drinking alcohol is a risk factor for liver cancer and more than 50 studies have shown a link between drinking alcohol and colon cancer.Source: Center for Disease Control and Prevention
