The two main types of lung cancer are small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC).
Lung cancer causes more deaths than the next three most common cancers combined (colon, breast and prostate).
Lung cancer is the leading cause of cancer death and the second most common cancer among both men and women in the United States, and is the leading cause of cancer-related mortality around the world. The National Cancer Institute estimates 224,210 new cases and 159,260 deaths from lung cancer (NSCLC and SCLC combined) in the United States in 2014. In 2008, approximately 375,000 Americans were living with lung cancer.
NSCLC accounts for approximately 85% of all cases of lung cancer. The overall five-year survival rate for patients with NSCLC is less than 15%, and this rate has for the last three decades remained largely unchanged.
