How often are colonoscopies performed for screening beyond initial recommendations?

• A. Every 10 years
• B. Every year
• C. Every 5 years
• D. Every 2 years

Answer: (A)

If a screening colonoscopy comes back normal, the next test is scheduled far enough in the future to reflect how slowly colorectal cancer develops and how thorough colonoscopy is at detecting and removing any problems when they appear. With no polyps or other findings, most guidelines recommend repeating the test about every ten years in average-risk adults. This long interval avoids unnecessary procedures, reduces risk from the procedure itself, and fits the slow progression of disease while still allowing for effective detection when it’s needed. Shorter intervals like yearly, every five years, or every two years would lead to many unnecessary procedures without providing additional protection for someone with a clean exam.
