I forget what this is called in medicine but someone linked about this on HN before. What I remember is this idea that there are so many things _that are wrong with all of us_, at any given time, that calling attention to and treating all of them would be more harmful than helpful. I think bodies being perfectly healthy is probably not how it works, it's more so that all the "bad" happening never rises to an emergent level.

Unnecessary medical treatments can have serious consequences. Even if you are absolutely certain you have a given condition, some treatments are very not worth it. More importantly, any given scan misses tons of important potential health issues. Not just the fact that CT scans don't show signs of MS vs MRIs, but neither of them will tell you about many cardiovascular conditions. So time spent treating made up issues from CT scans you don't need may be better spent doing other regular exams instead. Meanwhile, many aggressive cancers will be far too fast for any reasonable scan interval to catch in time. (And CT scans, to my understanding, can miss tumors early on, since it can't see as fine of detail as MRIs.)

I might avoid it because in reality the odds of it finding "something" are high, and the odds of that "something" being benign are high.

And then it's likely the options are 1) get a non-risk-free test, or 2) have constant anxiety about it (at least in my case)

Can I repeatedly press the button? Because then I'm pressing it, seeing what's up. Trying whatever low evidence/low risk method there is to "fix" it and then pressing it again.

Assuming there's no side effects to pressing the button of course.
