I used orgovyx. It was the RO's drug of choice. The conventional wisdom seems to be a) it's more even as you suggest since you take it every day. b) It's not a shot, so less painful and c) the belief is that you recover from the side effects more quickly. I really don't know about the 3rd one.

I would've have thought the thing to do, depending on other medical history, would be ADT for a few months then a targeted radiation to that tumor. (others likely will have more info)

I think getting a straight answer is tough because there are a lot of other variables, such as insurance coverage. If I recall the Orgovyx was about $80 per pill in the US, I was lucky and it was all covered but not everyone is in that situation. Maybe Lupron is covered and Orgovyx isn't etc.. Without getting too far up on my soapbox, unfortunately, a lot of docs here in the US seem to answer questions based on things like that instead of what is medically best for us.

There also may be something in your medical history that makes one better than the other.
Best of Luck to you!
