At least one person in my time here had to go from a dose in the teens of units, to over 50 between SRT and when it started to work. He also had IAA which complicates things. It’s not like SRT hits all at once. The tumour cells are neutered by SRT, and it’s just the normal life cycle of the tumour cells dying off that reduces the tumour and it’s effects. Not to say that it can’t get a little exciting. If in doubt, be cautious. I haven’t yet seen anyone switch to Prozinc after SRT. Hypophysectomy or surgical removal of the pituitary, could be a different story. The effects there are much more immediate. You are testing more than enough to keep Rocket safe. At night, if he is pink at PMPS and about the same at +4, go to sleep. And once he has hit nadir and started back up, you can ease off the testing until next preshot, especially while yellow or pink. Neko had a redo of her radiation, and the radiation oncologist described her tumour as “tiny” the first time. And it was smaller the second time. And the first redo he had heard of. It’s not common.
