I read most of the research on this topic. And it's all basically "overdiagnosing".

We had the same story about prostate cancer screening: "overdiagnosing", "people die with prostate cancer but not of prostate cancer", blah blah blah. It turned out that simply adjusting the aggressiveness of follow-up was enough to make prostate cancer result in significantly fewer deaths.

From my point of view: MRI is the ONLY tool that can catch things like pancreatic cancer before it's lethal.
