BC Cancer’s prevention program highlights a lesser-known but critical health risk—alcohol consumption increases the likelihood of developing cancer. In Canada, alcohol is responsible for approximately 7,000 cancer cases and more than 3,000 deaths each year. The latest data from BC Cancer shows that alcohol raises the risk of at least nine types of cancer, including breast, colorectal, liver, and mouth cancer. This happens because alcohol is broken down into chemicals that can damage DNA and cause inflammation, leading to uncontrolled cell growth. Despite alcohol being widely accepted as part of social occasions, the health risks remain largely overlooked.

BC Cancer emphasizes that even small amounts of alcohol contribute to cancer risk. Their guidance notes that consuming just three standard drinks per week increases the likelihood of developing cancer, while seven or more drinks per week place individuals at even higher risk. A standard drink includes a bottle of beer, a glass of wine, or a shot of spirits—what matters most is the total amount of alcohol consumed. Additionally, alcohol interferes with the body’s ability to absorb essential nutrients, further weakening its defenses against cancer.

The positive message from BC Cancer is that reducing alcohol intake can significantly lower cancer risk and offer other health benefits, such as better sleep and more energy. The organization encourages practical steps like tracking alcohol consumption, setting weekly limits, and opting for non-alcoholic alternatives. Even small reductions can make a meaningful difference.
