> OTOH, I have yet to hear a story from someone who had some sort of scan done, found something worth to take a look at, that then turned out to be nothing and, for some strange reason, had its life significantly affected by that.

My friend's wife had a scan done when she was 55 and they found "something they wanted to look at" in her breasts and needed to do a biopsy.

She has anxiety. Her blood pressure spiked to a dangerous zone. It stayed elevated even as they tried to control it with medication. It didn't go back to normal until the biopsy came back negative.

During that time, she was at significant risk of having a stroke or heart attack. All for eventually nothing.

Things like women who have a small cancer that is treated with suregry and quick radiation but insist on getting a mastectomy are not rare, either.

Humans are not rational.
