Summary

This study follows 8,000 adults in Denmark who are getting a screening colonoscopy for colorectal cancer. Researchers want to know how much pain or discomfort people feel during the procedure and whether that affects their decision to come back for another screening two years later. Participants fill out a short questionnaire right after the procedure, and their future screening participation is tracked through national registries.

What could go wrong
