Hypnosis could take the fear out of colon cancer screening
NCT ID NCT05051046
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using hypnosis during a screening colonoscopy helps people feel less anxious and in less pain, and whether it helps doctors complete the exam more fully. About 600 adults in France will be randomly assigned to receive either standard care or hypnosis during the procedure. The goal is to see if hypnosis is a good option to improve the experience and quality of colorectal cancer screening.
