Are the odds hugely in favor to leave it be? Sure, if you reason in terms of simple risk-adjusted years until death, it's an easy decision.

If you look at it in terms of outcomes beyond life/death, the calculations become more vague-ish. Is "fixed or dead" possibly preferable to risking negative outcomes with life-long impact? (If you live in the land of capitalism worship, a huge part of the decision is "can I currently afford this medical care, and do I think I still can in a few years")

It's certainly a difficult decision, but it is some that should be up to individuals. We shouldn't have doctors make that decision on your behalf, as if they somehow knew better. We should educate doctors on how better communicate risk, and how to talk about possible impact. (Most medical professionals switch to "deer in headlights" when you want to talk about probabilities of outcomes, and certainly can't explain them well if you even get them to talk)
