  • Despite higher lifetime consumption linking to greater risk, moderate drinkers had lower risk than heavy drinkers, and people consuming no more than one drink weekly showed no increased risk.
  • Federal health officials now advise people to `consume less alcohol`, and study authors urged reducing intake across adulthood to lower bowel cancer risk, while earlier this month the American Cancer Society reported colorectal cancer leads deaths under 50.
  • Experts say many cases are preventable and list heavy drinking, smoking, obesity and diets high in processed meat as risk factors, estimating more than half of cases are preventable.
