If you are younger than 74 (inclusive) with a personal history of precancerous lesions:
Findings from prior coloscopies and your family history will determine the timing of future colonoscopies or whether you return to screening with fecal immunochemical test (FIT).
If you are younger than 74 (inclusive) with a significant family history of colon cancer:
Colonoscopy is recommended every five years.
Significant family history means that you have:
- One first-degree relative (mother, father, sister, brother, daughter, or son) with colon cancer diagnosed under the age of 60; or,
- Two or more first-degree relatives with colon cancer diagnosed at any age.
Colonoscopy screening can start at whichever age is youngest between the following:
- Age 40; or,
- 10 years younger than the age of diagnosis of your youngest first-degree relative that was diagnosed with colon cancer.
