I don't know the specific answer to your question. But my experience has been that every step, every appointment takes time, more time than it should. I would recommend that you go ahead and schedule your appointments as soon as possible, then cancel them if your plans change. I did this and I was up front with all doctors as I was making the appointments ("Is it okay if I schedule this now, knowing I might cancel it later on?") and they all were supportive. I'd say you will want to talk to a Urologist about surgery, you will want to talk to a RO about radiation therapy, maybe others. Go ahead and schedule those appointments now.

For a 2nd reading of your biopsy, Dr Zhou is one of the best in the world. There is a fee (maybe about $500). He responded to my email ASAP.
