A colonoscopy is generally recommended every 10 years starting at age 45 or 50 for most people at average risk of colorectal cancer. If there is a family history of colorectal cancer or other risk factors, screening may start earlier and be done more frequently, such as every 5 years or even more often depending on individual risk. After removal of polyps, a follow-up colonoscopy may be recommended in 5 years or sooner if needed. People with conditions like inflammatory bowel disease might need colonoscopies every 1 to 3 years. Screening often stops around age 75 to 80 depending on individual health.
Summary of Recommendations:
- Average risk: every 10 years starting at age 45 or 50
- Family history or higher risk: start earlier, often every 5 years or as advised
- After polyp removal: typically every 5 years or sooner
- With inflammatory bowel disease: every 1 to 3 years
- Screening may stop after age 75-80
These guidelines can vary based on personal health factors and should be discussed with a healthcare provider.
