With the participants help, the investigators aim to track treatment methods, treatment outcomes, and adverse events, as well as document the treatment strategies used during endoscopic colorectal cancer prevention and treatment. This will allow us to verify if the results from targeted clinical studies and current scientific knowledge are also reflected in the real world. Additionally, the investigators want to use the collected videos and findings to support the training of doctors.
