  1. The non-smoker and NSCLC served as negative and positive control for lung cancer, respectively. Asthma sufferer and COPDs were included to test whether the diagnostic test can differentiate lung cancer from those who may have other respiratory diseases which share similar symptoms. The smokers consisted of high-risk population for LC who were not diagnosed with any cancer. Other cancers (i.e., breast, prostate, pancreatic, and colon-rectal) were included to ensure that the diagnostic test was specific to NSCLC
