Did you read http://en.wikipedia.org/wiki/Overdiagnosis? (See emails below)
If not, proceed no further. Even if you think you know everything, you still have to read it.
If you have, then this graphic should look familiar:
Overdiagnosis Bias: The over-inflation of survival statistic by “early diagnosis”.
So, now think about these questions:
- More lung cancers are detected in screened populations than in unscreened populations. True or false?
- What are some examples of “pseudodisease” in the case of lung cancer screening? (“the small solitary pulmonary nodule”)
- What reactions have your patients had from a CT scan that requires follow up to rule out cancer?
