The PSA test is no longer broadly recommended for prostate cancer screening [1]. What harm could it do, you know more about your body, even if it's a noisy predictor? Most prostate cancer is slow growing, and something that men "die with" rather than "die of", so treatment can make for worse outcomes, without clear benefit.
It's not clear that we have the health infrastructure in place to know what to do with frequent, low resolution, whole body scans of the human body. How often do anomalies show up and then go away? How often are anomalies purely a scanning/data processing artifact? Who reads the scans and makes recommendations about follow-ups, if any? I think this is the kind of thing that sounds exciting and with low direct risk, but with all kinds of questions that are not only unanswered, but apparently unconsidered.

Yes. I spent a bunch of money on many of the optional extra imagining scans on my last health check up only to realize this afterwards. Humans have survived this far without this data. It would be better to spend resources on preventative things or lifestyle things known to promote health, than to obsess over seeing whats going on inside.

This is exactly my thinking. There are decades of longitudinal studies behind the recommendations physicians make based on given levels of e.g. cholesterol in a standard blood test. And critically, those depend on standard protocols around administering and testing samples.
This would be brand new and would not have any of that infrastructure. Which all tech starts at, good. But I would expect Midjourney to need to dig in for a few decades to get and analyze clinical results and outcomes.
For body scans, I think about how few people would know if they have e.g. three kidneys (or other distortion), and how that impacts/doesn't impact their health.
Most people do not undergo autopsy after death, so it's possible there are correlates between good/bad health outcomes that frequent scanning would eventually reveal. But it would take significant time for this to be apparent.
