MONDAY, Feb. 27, 2017 (HealthDay News) -- Lung cancer remains by far the leading cancer killer because it is so often caught too late.
But researchers now say it may someday be possible to quickly confirm the disease after a CT scan, by using a simple nasal swab.
The key is DNA-based "biomarkers" in the nasal passages that appear to reveal whether a lung lesion is cancerous or not.
"Nasal gene expression [production] contains information about the presence of cancer," explained study co-author Marc Lenburg. He believes the nasal swab "might aid in lung cancer detection."
The researchers said the test might help doctors spare some patients expensive and risky follow-up procedures.Full Article
