I was recently diagnosis with PCr I found this podcast incredibly interesting, although its American, the treatments seemed very similar to those I am experiencing in UK.
He goes into great detail about all apects, PSA testing, MRI, biopsy, AS, and why/how these things develop in the first place.
It's free, and I am in no way connected to the podcast, and as a newcomer to this world I found it very helpful, and hope others might too, so I hope this post doesn't contrevene any site rules and get blocked.
