Where the nose is going to help the eye: Sniffing lung cancer

Lung cancer screening is by many seen as the way to improve cancer survival. Both the NLST and the more recent NELSON trial support this notion but there is ample space for improvement [1,2]. For one, the false positivity rate of low dose CT based screening is a serious issue, further subjecting persons with an incidental nodule to invasive biopsy procedures and putting a psychological burden on these patients [3,4]. If there are fewer false-positive nodules, there is less need for further work-up and the risk of complications, especially from invasive diagnostic examinations including surgery.
