The doctors at Georgetown recommended Cyberknife a couple of years ago, but said that treatment wasn't urgent so I stayed on active surveillance. When my PSA started going up again they recommended treatment with Cyberknife plus homone treatment with Orgovyx. When I asked why they were recommending hormone treatment now, but didn't recommend it two years earlier, they said the different was that Orgovyx was now available. They regard Orgovyx as superior to Lupron etc., in that it is better tolerated and has a faster recovery.
As to Cyberknife, suggest you look at some of the online videos about it. It is really amazing. 5 Cyberknife treatments are equivalent to 40 regular radiation sessions.
