Colonoscopy

I had colon cancer 2021.lucky my cancer polyp was removed.  I went for colonoscopy 2022.they found benign polyps. I went again on 23rd January 2026. It was so painful & not clear enough. I didn't have sedation which was probably a mistake. I have to go back in about 6 weeks time. Im terrified in case it doesn't work again. 68 year old male
