Lung cancer is the most lethal cancer, responsible for 28% of cancer deaths and killing ~1.3 million people worldwide every year. Diagnosis and treatment of lung cancer in its early stages could increase the 5-year-survival rate 3-4 fold with a potential for cure4, 7. Therefore, the main goal of this study is early detection of lung cancer, and specifically focusing on the volatile biomarkers of lung cancer that will assist in easy, inexpensive diagnosis based on our previous findings.
