Hi Photoman,
Thanks for posting on here!
I can imagine this is quite a shock for you. I can't offer any advice other than letting you know that my Father is going through Prostate Cancer and perhaps like you, it literally came out of the blue.
For him, he was expiriencing pain in his legs that came from nowwhere really, went to a doctor - test after test and it appears he has Prostate cancer but unlike you, his has perhaps spead to parts of his bone.
Photoman - I hope you've taken the time here to find what you are looking for and perhaps connected with someone directly affected by a similar cancer... and of course, similar treatments.
Best of luck and be sure to keep us posted on how you beat this
Regards
John
