It wasn't too unpleasant at all really, and I decided to go without any sedation so that I could get away as soon as possible. The procedure was much longer than anticipated though, because they found a load of polyps to remove - nine of the buggers. They told me it would probably take 20-25 minutes, but it was nearly an hour. It wasn't the colonoscopy that I was concerned about anyway, rather what they might find. Every time the doctor took out a polyp, he would say 'Adenoma, high confidence' and I was thinking 'Adenoma sounds like cancer', but it turns out that these are normally benign polyps. They've sent them all for testing though, and I get the results next Tuesday. Still a bit scary.
I have to say that the whole process, from getting the screening test to this stage, has been handled brilliantly by all concerned. First class.
Wishing you all the best Stroller
