Hi Christopher,
Very frustrating, isn't it. We know there's something going on, but can't get an answer..
Sounds like your urologist has access to more sophisticated tools than at my military hospital. So far all I've seen are PSA blood tests and TRUS biopsies. My third biopsy was 24-core samples. Not sure how many samples there are in a saturation biopsy, but I'd definitely opt for that...
My "update" is that my urologist called yesterday with the results of my 3rd biopsy. He said he found the cancer. The only specific info so far is that I have a Gleason score of 6. I have an appt to see him in the morning, so I hope we'll have a clear path by tomorrow afternoon.
From a close friend who has been through the whole process, including radical prostectemy, they apparently can not determine if the cancer has spread until they remove the prostate and surrounding lymph nodes, so I expect it will be a while until I am fully confident in the results, whatever they are.
Good luck with your search...there's something going on, you have to find out what.
Cheers, Billy
