What would happen if they just left the bit in his lung? I wonder what the body would do to this foreign object, maybe just wrap it up in scar tissue. Or would it cause some kind of inflammation that would be detrimental to the organ?
A few years ago, I was getting a root canal done on one of my front bottom teeth. The sliver of a drill bit broke off in there, and there will stay. It’s totally apparent on x-rays, and luckily it doesn’t set off metal detectors at airports.
