I am all for active surveillance if recommended, and a friend has been on it for five years whilst enjoying life to the full.
If you have private health insurance it might be worth having a consultation with one of these ‘top’ prostate surgeons, as recommended by their peers, to see if a prostatectomy is possible subsequent to the previous surgery.

My own surgeon, who we call Professor ‘Whocannotbenamedhere’, for he cannot be named here, is a world-renowned prostate surgeon, and you could find out about him if you Google ‘Santis prostate’.
Best of luck.
Cheers, John.
