Hi Pat
Can you provide more detail e.g. PSA scores before and after his op. What did the histology report say. How do you know the cancer has come back?
If you read my profile you will see I saw an oncologist not long after my operation. I had follow up RT and 3.5 years on my PSA is 0.02.
So it doesnt mean it's progressed to grade 4. It may just mean there are a few stray cells in the prostate bed that need dealing with.
See what the oncologist says
