Yes, absolutely it's between you and your medical team.

Since my treatment has kept my PC totally inactive for 2½ years now (undetectable PSA), my onco team and I are happy to hold chemo in reserve for the future, rather than using it now when there seems to be nothing active for the chemo to fight (maybe a relatively few deeply dormant cancer cells hiding out among billions of healthy ones).

The videos I watched about the triple treatment referred, I think, to castrate-resistant metastatic prostate cancer or non-oligo-metastatic PC, but I might be misremembering, and also, of course, I'm a layperson as well.
