| Age | Rates increase with age; the vast majority of cases occur after age 50. |
| Gender | Incidence rates are slightly higher in males. |
| Genetics | Specific genetic alterations have been recognized in several hereditary conditions with high risk of colon cancer such as familial polyposis. These conditions account for about six percent of colon cancer cases. |
| Diet | Strong evidence that diets high in fat and low in fiber contribute to increased risk of colon cancer have been shown. |
| Other | Individuals with a close family history of this cancer and those with a personal history of certain other cancers are at increased risk. Regular, moderate physical activity is associated with lower rates of this cancer. |

There is a steep increase in rates starting at age 50 onwards, peaking at the 75 to 84 age interval in both males and females. Males consistently have a higher rate for all age groups until age group 75-79 when the rates for females become higher than the rates for males.
