@tjv1156 asked ❝why did your team say your cancer *will* return?❞

Because I'm stage 4: my cancer had already metastasised to my spine before it was diagnosed.

Received wisdom at the time was that castrate resistance on ADT would last only 18–24 months, then I'd have to progress to other measures like chemo or Pluvicto, and I'd die a couple years after that. But that was before there was as much data from new clinical approaches like starting on an ARSI early instead of waiting for castrate-resistance, treating oligometastatic cancer with "curative intent," etc. Things look much more promising for us now.
