Summary

This study compares two ways to prevent colon cancer in people who have had multiple advanced polyps removed. One group gets a standard colonoscopy after three years, while the other group does a simple stool test every year for two years, and only gets a colonoscopy if the test is positive. The goal is to see if the stool test approach catches new dangerous growths earlier and reduces cancer risk. About 940 adults aged 40-75 who have had at least two advanced polyps are needed.
