Why aren't there screening tests to detect lung cancer early?
Screening to detect lung cancer early sounds like it makes sense, because treatment outcomes are better the earlier you catch the cancer. But only those at high risk really benefit from screening. The reason is that the screening tests, such as a CT scan, are overly sensitive and find abnormalities that end up not being cancer, but still require follow-up tests that are invasive and carry their own risks.
