Studies have demonstrated a link between alcohol consumption and an elevated risk of colorectal cancer.
Research now reveals that higher lifetime alcohol consumption is also associated with a higher risk, especially for rectal cancer, and that quitting drinking can lower a person’s risk. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
Current drinkers with an average lifetime alcohol intake of ≥14 drinks per week (heavy drinkers) had a 25% higher risk of developing colorectal cancer and a 95% higher risk of developing rectal cancer compared with those with an average lifetime alcohol intake of <1 drink per week (light drinkers).
