Summary

This study tests whether sending an early letter with information about colonoscopy—either from the screening center alone or co-signed by the patient's own doctor—can increase the number of people who get a follow-up colonoscopy within 6 months of a positive colorectal cancer screening test. About 2,000 adults aged 50-75 in central France will take part. The goal is to reduce dangerous delays and improve cancer prevention.
