 This research paper proposes a new method for detecting lung cancer based on the analysis of exhaled breath condensate samples. This method uses two genetic markers, Gata6 and NKX2-1, to identify patients who are at risk of developing lung cancer. The results of this study show that the combination of these two markers can accurately predict the presence of lung cancer in patients. Furthermore, this method has been validated in an independent cohort of patients, demonstrating its accuracy and reliability.
