This is a tricky bit. There is a lot of interplay here between medical professionals and the general public, and not all of that is either rational or ethical. But absent symptoms non-treatment is better than treatment.

Data about unnecessary procedures is relatively plentiful, which is of course sad, whether that's driven by commercial incentives or the need for 'something to be done' is not something that I have any grip on but it certainly is problematic.
