In fact this is not even unsaid. My mom suffered a transient ischemic attack last week. To quote the surgeon: statistically she had a 15% chance of issues in the coming weeks. An operation has a 5% risk of complications, so normally we don't perform one. But 5 is lower than 15%, so let's do it. Not sure of the math, because I assume the 15% is spread (non-linear) over the 2 weeks, and she was operated at the end of the window, but it is still amazing that all of this is possible.
