Screening > overdiagnosis > overtreatment > harm

There is no doubt in my mind that screening has, in general, been oversold, represented in some cases as a magic bullet that will save far more lives than it actually can. It’s been a relatively recent realization on the part of physicians that overdiagnosis is a real problem because it leads to overtreatment, which can cause harm. --David Gorski, oncologist

More physicians are now aware of the problem. But the general public must be informed for they're the ones who are harmed.
