The Claim
The current epidemiological definition of overdiagnosis in lung cancer screening, which defines overdiagnosis based on death from an unrelated cause rather than cancer aggressiveness, results in clinically inconsistent and paradoxical interpretations, including the labeling of aggressive cancers as 'overdiagnosed' when patients die of non-cancer causes such as heart disease.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If someone gets screened for lung cancer and finds a tumor, but then dies of a heart attack instead of cancer, doctors might say the tumor was 'overdiagnosed'—even if it was deadly. This doesn’t make sense to many doctors because the cancer could’ve killed them if they hadn’t died of something else first.

What the research says
1 studyStudy: Overdiagnosis in lung cancer screening
The study says using death cause to decide if a cancer was 'overdiagnosed' doesn’t make sense—like calling a dangerous cancer harmless just because the person died of a heart attack. It agrees with the claim that we should judge cancers by how aggressive they are, not by how people die.
