Are people really going to perform invasive procedures over mere concern if there are no symptoms and the doctor recommends against it?

People take horse dewormer against COVID so yes they will do all kinds of irrational things

Oh we're still doing the "horse dewormer" thing despite 250 million humans taking it each year?

Yes, because it's nonsense and those 250m humans need to get off Twitter.

250M people take it as an anti-parasitic, as they should.

There are numerous comments here from experienced people addressing this. Yes, that happens and a doctor who dismisses the concern can be sued for malpractice if something actually does show up, so they are put in a difficult position. For some reason you just assume that doctors will recommend against an invasive procedure when there is a positive tomography result.

Review the numerous comments that address this as a statistical issue -- which it very much is when talking about the scale that Midjourney is claiming.
