ColonCancerCheck(CCC) recommends that men and women get screened with a colonoscopy if they have a family history of colorectal cancer that includes one or more first-degree relatives (parent, sibling, child) with the disease. This applies to people who feel perfectly healthy and have no symptoms. Screening should begin at 50 years of age, or 10 years earlier than the age their relative was diagnosed — whichever occurs first. People at increased risk should speak to their healthcare provider about a colonoscopy.
