I just received a message from the NHS inviting me to go to the hospital for bowel cancer screening. They seem to have me on their list as I only just went for the heart check as I have reached 55. Has anyone had it done? It looks as if they stick a probe thingy up your how's-yer-father and poke about at any polyps they bump into. The paperwork says it is painless, and having been sent to boarding school, it won't come as a surprise, but I wondered how uncomfortable it is?
