Lung cancer is the main cause of death in the United States and around the world. The two types of lung cancer are non-small cell lung cancer and small cell lung cancer (around 15%). In spite of advances in early diagnosis and standard treatment, non-small cell lung cancer is regularly analysed at advanced stages and has a poor prognosis. The treatment and prevention of lung cancer are major needs that can most likely be enhanced by a better understanding of the molecular process in cancer and development of cancer. Non-small cell lung cancer can be characterised into three subtypes: squamous-cell carcinoma, adenocarcinoma, and substantial cell lung cancer. Smoking causes a wide range of lung cancer, however, is most firmly connected with small cell lung cancer and squamous-cell carcinoma; adenocarcinoma is the most well-known in patients who have never smoked
