Yes. There is no doubt that drinking alcohol can cause at least seven types of cancer: those of the mouth, gullet (oesophagus), throat (pharynx and larynx), liver, large bowel (colon and rectum), and breast.
Consumption of any amount of alcohol increases your cancer risk. The more alcohol you drink, the higher the risk of developing cancer. Reducing your consumption or – even better – avoiding alcohol completely will help reduce your cancer risk.
