No one can tell you how long you have. You may live long enough to have something else kill you. You don’t mention what drugs you are on. You don’t mention your biopsy results and other information like current PSA in this message. You may have done that in another set of messages, but there are so many people. It’s impossible to really keep up without the information being supplied In the current thread.

If you stopped taking Xtandi, And are now taking nothing, then you need to get on something right away to stop your cancer from spreading. Ask your doctor what he thinks. It sounds like you were not a good choice for taking a drug holiday. If you’re just on an ADT drug like Lupron You must be resistant and need Xtandi or Darolutamide (Nubeqa) which has fewer side effects

Can you have SBRT on those three new spots, or do you have so many that they do not want to do that?

Definitely get that PSMA PET scan before making any real decisions. If you can have SBRT on those new lesions, then you can put off Pluvicto.
