I'm sorry but that is a very naive and honestly wrong take. An "extra scan" is not just giving anxiety. It raises cancer rates. It can discover underlying relatively bening conditions which affect insurance coverage, for example. It can cause anxiety. It takes away resources "just to make sure". At the scale you are proposing, false positives are a massive issue that you simply cannot ignore. It is all but trivial.
This is it, I am not sure how people can be so dismissive about the risks of over diagnosis.
However, usually there are studies done to carefully weigh the risks and benefits of testing likes this. I would expect tests like these to become the norm for screening at risk populations at some point (usually people beyond a certain age or people with family history).
