Is There a Harm in Over Diagnosis?

Over diagnosis is a vexing problem, but i think there are some steps forward that we can take. We never think really of the harms of testing. And if we do believe in these, then we should obtain a thorough consent. I just gave a lecture to the medical students in calgary on over diagnosis. This is the first time they've come across this topic,. vere the first time it's been presented in medical a curriculum.
