What is the correct frequency for colonoscopy in individuals at risk for FAP?

In individuals at risk for Familial Adenomatous Polyposis (FAP), surveillance colonoscopy is critical for early detection of colorectal cancer, as FAP leads to the development of numerous polyps that can become malignant if not monitored and managed appropriately. The standard recommendation for those at risk is to begin colonoscopy screening typically around the age of 10-12 years. Once the first colonoscopy is performed, if no polyps are found, the follow-up colonoscopy is usually recommended every 1-3 years. However, if polyps are detected, surveillance frequency may need to be increased to annually.

The correct answer aligns with the general guideline to perform colonoscopy every 1 to 2 years for individuals at risk for FAP as they transition to adulthood, with the emphasis being on yearly surveillance rather than a less frequent schedule. Although the option indicates a specific interval of every 10 years, which generally applies to average risk individuals, it is not adequate for those with a genetic predisposition like FAP. The increased surveillance schedule reflects the need to catch any polyps that develop early enough to intervene before they progress to cancer.

Therefore, while the choices are structured around varying intervals, the standard protocol indicates the need for closer
