The risk from screening, and the risks from further diagnosis and accidental treating of false positives can be much higher than the disease itself as long as it is rare enough.
If CT scans are performed on more than 5% * (1 + false positive rate) of suspected cancer cases, having a CT scan in the history of 5% of cancer cases is entirely expected.
I took a preventative MRI run by an ML/AI company that the healthcare folks say is a bad idea. I didn't discover any hidden cancers but they did find 1-2 emerging health issues that were preventable with simple diet and lifestyle changes.
If everyone showed up to their doctor asking for preventative imaging, it would overwhelm doctors since there aren't enough resources to treat everyone who is sick. Your individual health will always be less important than the integrity of the system.
You would have no idea you had it without imaging, since in the early stages you feel nothing.
Now I can work to build up muscle around that area and avoid over exerting that part of my back, instead of dealing with pain and being prescribed opiates in 20 years. Another example of how the system has killed countless people and absolutely failed the public.
From 30 years of age, disc degeneration is more likely than not. You don’t need a scan to tell you you’re in the early stages of it.
Everyone is going to get a bad back at some point if they don't take care of themselves.
"Eat right and exercise " is very generic advice, but it's cheaper than an MRI and will prevent more disease.
Sounds like the exact same results you'd have gotten without imaging.
