Diet may play some role in determining the incidence of colorectal cancers in the general population. Diets high in fat and red meat may be associated with higher risk for the disease.

People who use aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) regularly (more than 16 times per month) have a lower risk of developing colorectal cancer. Researchers are still investigating the mechanism by which these drugs exert their protective effect. Calcium supplements may also reduce the risk.
