Hello Mark,
So sorry you find yourself here, however there's lots of very helpful people, info and advice on this forum.
We've been where you are, waiting for results is hugely stressful and worrying. It's very hard to think of anything else but it does get easier once a plan is in place for treatment.
I was a similar age to you (48) when diagnosed. Whilst waiting for my bone scan results I was convinced the pain I was having in my big toe must be the cancer. Luckily all was clear and it was more to do with my poor football skills that caused it!
If you don't mind me asking what was your PSA result and what brought you to be tested?
Generally prostate cancer is slow moving so you should be able to take your time choosing which treatment path you want to take, don't feel rushed.
I took the RT/HT route in the end, if you click on peoples username's it will take you to there profile which most people use to detail the diagnosis and treatment
There's a useful video that goes through the various treatment options, I see if I can find it, someone else may well beat me too it!
All the best
John
