How to Use the Endoscopy Screening Interval Calculator
Screening recommendations for upper endoscopy and colonoscopy differ significantly in the US compared to countries with higher stomach cancer rates. This calculator enters your age and family history of stomach or colorectal cancer to show the recommended approach for each exam, whether you're currently eligible, and how often each is suggested.
Because stomach cancer incidence is comparatively low in the US, routine upper endoscopy (EGD) screening is not recommended for average-risk adults with no symptoms. It's generally reserved for people with elevated risk — a family history of gastric cancer, certain hereditary syndromes, or specific ethnic backgrounds — in which case your doctor decides on an individualized schedule rather than a fixed interval. Colonoscopy, on the other hand, follows clear USPSTF guidance: average-risk adults start at 45 with a colonoscopy every 10 years, while those with a family history are typically advised to start around 40 and repeat every 5 years.
This tool reflects standard guidance for adults without symptoms. If a prior exam found polyps or other findings, follow the individualized interval your doctor recommends rather than these defaults. And regardless of your screening schedule, symptoms like unexplained weight loss, persistent indigestion, or blood in your stool warrant seeing a doctor right away. This result does not replace a medical diagnosis, and your exact screening plan should always be decided together with a healthcare professional.
Frequently Asked Questions
No. Because stomach cancer rates are much lower in the US than in some countries, routine upper endoscopy screening is not recommended for average-risk adults. It's typically considered only for people with specific risk factors, such as a family history of gastric cancer or certain hereditary conditions.
For average-risk adults with a normal result and no polyps, USPSTF guidance suggests waiting 10 years for the next colonoscopy. If polyps were found or removed, follow the specific interval your doctor recommends instead.
