Had both ends done a couple of months ago - found and removed a couple of polyps. Related this story to my boss, back in London, who is a good 10 years younger than me, and he said he was going for the lower option in a couple of days. Few weeks later he says he'd got the results and there is a tumour too big to remove by surgery, so he is now on chemo. Had his first session 2 days ago. For a boss, he's a decent bloke, so fingers crossed.
