I hope you get into the Tom Baker Cancer Centre in Calgary soon. I don't know what they'd be waiting for (I didn't have to wait for anything here in Ontario).

Note that "curative" refers to doses and intent, not result.

For example, I got a "curative" dose of radiation to my prostate (the normal max, 60 Gy) even though I'm stage 4 like you. That doesn't mean I'll be cured; only that it's a dose that oncologists use when they're trying to prolong a patient's life (curative intent) rather than the lower dose that they'd use just as-needed to help manage pain (palliative intent).

"Curative" isn't always good — it means that the patient is more likely to suffer pain and unpleasant side-effects (like the radiation damage I've experienced to the bottom of my bladder), so they don't want to do it if the chances of significantly prolonging life are low, because it will just cause unnecessary suffering and harm the quality of the life that the patient has left. I'm thinking of a friend's case — I don't disagree with his decision (he was only 60, and I'd probably have done the same) but I saw extra chemo and CAR-T really lower the quality of the last few months of his life after his lymphoma started to spread again.

(As always, layperson writing here.)
