I'm due to have a colonoscopy and I have managed to get in quite a state about it. The only reason that I am having one is my dad didnt recover from Colon Cancer and died when he was 44. So I have been pretty insistent to my GP that I go on a screening program, which looks like it is just about to start So on one hand its good that I will be screened but I've got really worked up about the procedure and if they find anything, no real reason why they should - no symptons etc. So any reasurrances will be gratefully received.
