As I’ve mentioned several times on here… Get yourselves tested!!
I was diagnosed at same age as Sir Chris is now, 48. Thankfully mine was caught at Stage 2 and was still contained in the prostate, which was removed 10 years ago next month and so far I remain cancer free.
There are a few GPs on here who will be along shortly, they usually are, to say that the PSA blood screening test is not much good and will only be applied by your GP if you have other risk factors, which is about right unfortunately.
In mu case, I was at the doctor anyway, on the back of a bad bike tumble, and mentioned that I was up at the loo a few times most nights, so he suggested checking my PSA as a precaution. It was elevated and they retested it a month later and it was the same, so that led to more tests and I had surgery a few weeks later.
If you have any concerns it is best to have a proper chat with your GP, and be aware that they may reluctant to do a PSA blood test if you have no other indicators of risk.
