Welcome aboard, it seems odd bidding people welcome to a place they really dont want to be.
But, since you're here, you may as well get the most from the forum.
Adrian is absolutely right, the battery of tests and the resultant periods of waiting are so difficult to navigate. I was told at the start of my biopsy that, based on the mri results and PSA of 4.84, I definitely had prostate cancer and that this test would simply show what type. Cue being absolutely terrified for the next five weeks.
When no contact from the hospital became too much to bear I managed to get through on the telephone. I had been discharged, and they hadn't got round to telling me as they were "busy with people who really did have cancer".
I really hope that your "definitely have prostate cancer" becomes something much less serious, as mine did. You just never know with all these scores and numbers flying around.
I have a friend who is currently dealing with kidney cancer that has spread to his humerus, which he has had removed and replaced with a prosthetic one. Quite a plateful at just 49 years old. On Monday we found out his 24 year old son has testicular cancer which requires an immediate orchidectomy next week. The lad has gone through the whole diagnostic process alone because he didn't want to add to his parents stress, they only found out because he told his sister he was going in for the operation and she freaked out.
My own brief dalliance with PCa seems so minor in comparison to my friends situation. But I know how scared I was even at the mention of the possibility and how much it has affected my outlook on life in general.
All I can offer is my support and best wishes for your onward journey, however long or short it may turn out to be.
Take care and try not to worry until there is something to worry about.
Best regards Mick
