Doctors might be able to tell if a lung cancer is harmless and doesn't need treatment just by looking at its shape on a CT scan—solid or not—instead of waiting to see if someone dies from it.

Overdiagnosis in lung cancer screening

Narrative Review

2021 Feb

The study says we should judge if a lung cancer is harmless or dangerous by how it looks on a CT scan (like a fluffy vs. solid spot), not by whether the person eventually dies from it. This matches the claim that imaging features are a better way to spot cancers that don’t need treatment.

Similar Assertions

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.
