Colonoscopy pain may keep people from future screenings
NCT ID NCT07353632
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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 this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help improve how screening colonoscopies are done, making them less uncomfortable and encouraging more people to return for future screenings.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly change medical care. The results depend on people accurately reporting their experiences, which can vary widely.
