Research has shown that about 50% of colorectal cancers can be prevented by following a healthy lifestyle. Moderate to high levels of physical activity lead to lower rates of colon and rectal cancers, though this evidence is stronger for colon cancer than it is for rectal cancer. Eating healthy and nutritious foods can also reduce cancer risk.

Screening is an important preventative measure for colorectal cancer. In the general population, screening is recommended to start at age 50. All people aged 50-74 should receive a digital examination as well as a fecal occult blood test. Men and women at higher risk should have more frequent and thorough examinations, beginning at a younger age. Talk to your doctor about screening guidelines.
