It may sound trite but don't panic. KNOWLEDGE IS POWER! Being 61 and a PSA in the 10 range is not IT. You may want to at least have a PSA test monthly to see IF you have a doubling time.
I am a fan of a book entitled 'A Primer On Prostate Cancer' by a specialist named Dr Stephen Strum. There are others that you may want to read in order to ask great questions.
Educate yourself as best you can and then get 2nd, 3rd and even 4th opinions as to a plan of attack.
