* If relative diagnosed at &lt; 60 years old:

    * If no significant neoplasia appears by age 60 years, can offer expanding the interval between colonoscopies.

For patients with 2 or more first-degree relatives with colorectal cancer or an advanced polyp:
* Start screening colonoscopy 10 years before the reatives' youngest age at diagnosis or age 40, whichever is earlier. Repeat colonoscopy every 5 years.

Patients with a history of potentially precancerous polyps should follow shortest interval between recommendations above and recommendations based on colonoscopy findings.
