I am very sorry to hear that. As I've posted before, you're CEO of your care team, so you get to make the final decisions. When people are replying here, it's not to disrespect your decision, but just to make sure you have all the available information.

Even advanced (stage 4b oligometastatic) prostate cancer like mine is manageable now for many years, if not indefinitely, but it's not an easy road. If you're already elderly and or have a lot of other health issues, it makes sense that you might not want to put yourself through it. But I'll just add my personal experience that after two rounds of radiation and almost 3 years on ADT and ARSI (Erleada), I'm living a happy, almost-normal life, and just got back from a 2-week trip to Europe last month. I was young when I was first diagnosed (56), so that helped, but treatment might not be as bad as you fear right now.

That said, best wishes whatever road you choose, and keep us all informed. There's a lot of caring in this forum.
