@drcopp
I really agree with your post and reply: "I will ask my Dr. about bike riding and see what his advice is." Exactly what a poster on MCC should do when reading experience of others. I am glad you posted that reply.

Only your doctors not those on MCC have examined you and have your complete medical history and are medical professionals to give you specific advise and guidance on what to do and not do.

I agree the biopsy is going to give you Gleason Score not PSA. PSA is just what one poster posted some time ago that it is like a "check engine light." Need to check prostate gland.

And your doctor gave you really accurate medical advice. It is the rise of PSA not necesarrily the number that is of concern.

It really sounds from your post you have an excellent doctor. Good luck!
