That makes no sense at all, unless you're saying that people should respond to all such information by ignoring it.
There is a lot of space between ignoring and doing invasive dangerous operation after some blot was spotted on some imaging diagnosis.
In which case, why bother getting the information in the first place?
P.S. The responses ignore what I actually responded to, which was a claim that "The false positive thing is a nonissue" -- where the "thing" is 99% false positives. The only way to respond to information such that "the false positive thing" becomes "a nonissue" is to never respond to it at all. The responses to my comment all address some strawman.
yeah? give adequate accurate information to people and let them decide what to do with the information.
if someone told you, you had a .01% chance of getting a disease for example, aren't you better off with that information? even if it is noisy?
You could repeat the test, perhaps on a more frequent interval to keep an eye on it. You could follow up with a more specific test, or do confirming blood work. In the meantime you can adjust your diet as a precaution, or get motivated to get in shape just in case.
There's plenty of room between "go under the knife" and "ignore altogether."
