A doctor from Medlife Crisis explains in under three minutes why even a rich patient should not simply order every medical test, touching on pre-test probability and Bayesian reasoning. False positives make blanket testing counterproductive.
Why Hacker News points people here: HN people link it as a short, funny and accurate explanation of why over-testing and over-screening can do harm.

There's a great (and short) video suggesting why it's not a good idea to run as many medical tests as possible, and it's not because of the cost: this video

“a tumor is not necessarily dangerous”
Notes that a tumor is not necessarily dangerous
I get your point, however I think there are a few confounding things. For a lot of people, if you get a positive result from a test that a doctor brushes off that's not going to go well. I'm very much in favor of more testing personally, there are almost certainly folks who're on SSRIs who'd benefit more from Vit D/Mg supplementation for example. Another thing I seem to remember in his video was that a tumor is not necessarily dangerous. Out of a hundred (say) tumors in a person's life, only maybe 5 are risky. But I'm paraphrasing this badly. Edit: this video is one of the videos, however I think he's talked about this more (likely on instagram or another video too).
