This is more true than people realize. My wife and I got full body MRI scans.

Both showed "possible" medical issues. My though was "Great, I have a baseline, in two years I'll get another one and compare".

My wife on the other hand got a bit obsessed about her results and had what was probably an unnecessary procedure to biopsy something, which turned out to be benign.

I suppose you could argue that another way...better safe than sorry...but the stress that is caused by known uncertainty vs unknown uncertainty can be too much.
