John, who found a swelling in his abdomen before he got tested, added: "I had no reason to get tested for prostate cancer again - and there were no real symptoms apart from a swelling. So it's very important for men to get themselves checked out.
"Men tend to think - oh, that's a problem, but it will go away. They shouldn't do that - prostate cancer can be treated, and cured."
Common symptoms include:
- needing to urinate more often, especially at night - for example if you often need to go again two hours after urinating
- difficulty starting to urinate
- straining or taking a long time to finish urinating
- a weak flow when you urinate
- a feeling that your bladder has not emptied properly
- needing to rush to the toilet - you may occasionally leak before you get there
- dribbling urine
- However, early on, there are often no problems with urination.
