Looks great and hope your recovery is going well. Keep an eye on PSA bloods and so long as stable should be all good.
Looks like the reports eludes to clear surgical margins which is very good news.
With any amount of type 4 (medium grade) cells I’d always be inclined to act. Even type 3 (low grade) can metastasise and this risk increases with higher grades. Sooner out the better is usually the view certainly if age is on your side.
I would T2c Nx Mx 3+4 which meant it was in all lobes of the prostate but confined in terms of surgical margins. No lymph node or seminal vessel involvement . Think I had around the same percentage of type 4 which was an upgrade on my biopsy results which were 3+3.
mets are always a best guess but regular PSA bloods should keep this under the radar as they can pop up anytime even decades or so later.
best of luck with the recovery
