This then brings up the issue of injuries/illness that you can't heal from naturally, like amputation or cancer. Will granny's power work on those?

Honestly, I don't mind if they simply don't put a limit to the healing. Just heal him whenever he gets hurt until people get pissed at how irresponsible that is.
It's not "just doing it faster", it's using resources from your own body. That resource is called in this anime as stamina, and whatever encompasses stamina. So the believe here is that it's dangerous to force the body to go through a healing process that uses up some of these resources maybe to a point of depletion or something.

In a way it's like being put on a machine that forces you to run a marathon and you're only have stamina to withstand just 1 mile of running. What would happen then?

Again, we're talking about hypotheticals here and using the term stamina which is not all that scientific and intrinsically vague. That's why I introduced the other side of it, fatigue and then consider when your body goes beyond what it can handle fatigue wise.

That's how I'm seeing it.
