Well the results have come back and it's looks like I'm a lucky chap. I had two tumours removed from my bladder both of which are a low risk of recurring, and yesterday I had the Sigmoidoscopy where they removed a polyps which looked to be benign. I have to have regular check-ups but it's a small price to pay. It's been a worrying time for us but I'm glad I had the tests and can now look forward again, I feel that a great weight has been lifted from my shoulders. If it has taught me anything, it's that if your are in any doubt about getting a check up, just do it, the earlier it's looked at the better.
Now off to take the pup for a gently stroll and try to get fitter.
