It's not been normal to prescribe HT to men awaiting surgery. Prostate cancer is very slow-growing, and if the cancer is wholly contained within the prostate, HT really serves no purpose if the prostate is shortly going to be removed. It really only started being done when long delays for surgery were experienced due to Covid.
If cancer has been there for years, or even decades, as is usually the case, waiting an additional few weeks for surgery has no impact on the outcome.
Best wishes,
