The paradox of testosterone and ADT
Phil, It’s a curious thing, really — this blind devotion to testosterone as the prime mover in prostate cancer’s twisted little drama. One might imagine that a tumor emerging in an environment already barren of testosterone — my personal endocrine wasteland — might, out of sheer metabolic necessity, learn to dine elsewhere. Glucose, glutamine, maybe even sheer spite. In other words, it may never have been dependent on testosterone in the first place, rendering castration-based therapies about as effective as removing the steering wheel from a horse.
And yet, when I dared to suggest this — that perhaps my tumor was an evolutionary overachiever, already adapted to scarcity and thus indifferent to the standard hormonal starvation diet — I was met not with curiosity, but catechism. The gold standard, they said. Tried and true. As if medicine were a medieval guild and I, an unruly apprentice questioning the sacred text.
Now, don’t get me wrong — gold standards exist for a reason. They work. Mostly. But I’m not "mostly." I’m me. And my concern is not the statistical majority. It’s whether this doctrinal adherence overlooked a tumor that, by virtue of its very origin, had already found a detour around the testosterone toll booth.
So here we are: therapy proceeding with grim determination, and me quietly wondering if we’re starving a tumor that was never hungry in that way to begin with. And if that’s true, what then? Will the outcome reflect biology’s stubborn individuality, or medicine’s one-size-fits-all optimism?
Either way, it seems I’m not just fighting cancer — I’m also in a polite but pointed disagreement with protocol.

There are also facilities in Canada where you can pay for a PSMA PET scan, if your onco team doesn't think it's medically necessary to order it (my oncologist was actually cooperative when I floated the idea, but said it wouldn't likely give me much info as long as my cancer is castrate-sensitive and my PSA is undetectable < 0.01).
One lab I found in Alberta charges CA $3,200 (US $2,250), so perhaps that's the norm (?). There is also the option of popping across the U.S. border and getting the scan down there, but it might be more expensive.
