I'm not even in US and I'm considering the same.. if the expenses go above some reasonable threshold, I don't see the point of me living enough to see my family dragged into poverty. I don't delude myself - it's not easy to do.

Part of the problem is that, especially with an illness with as complicated a treatment process as many cancers, there's no way to even estimate the expenses. Even once you get treatment, the expenses might not be accessible until the bill comes in and you find out what your insurance company will pay for.

After that, there's a sunk cost issue: once you've dropped (N*your current net worth) on treatment, what's the harm in continuing?
