Abstract
Lung cancer is the prime cause of cancer death among both men and women according to WHO report 2.09 million cases globally. It is also the chief cause of cancer death among men and the second leading cause of cancer death among women worldwide. The lung cancer classified into two different types are small-cell lung cancers (SCLC) and non-small-cell lung cancers (NSCLC). Non-small cell lung cancer is more common than small cell lung cancer. Treatment of lung cancer may involve a combination of surgery, chemotherapy, targeted therapy, immunotherapy, and radiation therapy. Therapeutic recommendations depend on several factors, including stage and type of cancer. Low- and middle-income countries now account for more than 50 % of lung cancer deaths each year the responses to current standard therapies are poor except for the most localized cancers. The purpose of this review is to sum up the types, epidemiology, detection, metastasis and the treatment of lung cancer. Key words: WHO, SCLC, NSCLC, Epidemiology, Metastasis
