As these cancers did not cause the person's death, identifying them would have represented overdiagnosis rather than useful medical care.

However, the "presence of false positives alone does not indicate overdiagnosis".

That phenomenon, overdiagnosis, is a recognized consequence of increased screening, medical researchers say.

Thus most of the inferences about overdiagnosis comes from the study of populations.

This example demonstrates how survival rates can be increased by overdiagnosis, even if no one avoids death.

The less familiar, but more worrisome, harm comes from overdiagnosis and overtreatment.

If there were overdiagnosis, sticky-diagnosis would induce a higher cancer death rate in the intervention group than actually the case.

Testing may lead to overdiagnosis and unnecessary treatment.

This situation, called overdiagnosis, puts men at risk for complications from unnecessary treatment such as surgery or radiation.

Even in regions where the disease does exist, scientists say, there is tremendous overtesting and overdiagnosis.

While failing to make a diagnosis can result in lawsuits, there are no corresponding penalties for overdiagnosis.

Dr. Welch and colleagues assert "overdiagnosis" more generally but offer no evidence.

And if screening (or testing for some other reason) detects these cancers, overdiagnosis has occurred.

In fact, some degree of overdiagnosis in cancer early detection is probably the rule, not the exception.

There may be mismanagement and overdiagnosis, and children react to medication in different ways.

Although overdiagnosis is almost impossible to document in a living individual, autopsy studies suggest that many individuals die with lung cancer rather than from it.
