When should endoscopic screening begin for individuals with a family history of CRC? How often should endoscopic surveillance be performed in these individuals?
- Endoscopic screening for CRC should begin at age 40 or 10 years younger than the affected relative in individuals with a first-degree relative with CRC.
- Surveillance endoscopy should be scheduled every 3 to 5 years if the relative was younger than age of 60 at diagnosis.
- Individuals with a first-degree relative with CRC or advanced adenomas diagnosed at age 60 years or older can be screened like average-risk persons.
- Patients with a second- or third-degree relative with CRC should adhere to average-risk screening recommendations.
