Lung cancer facts
- Lung cancer is the number one cause of cancer deaths in both men and women in the U.S. and worldwide.
- Cigarette smoking is the principal risk factor for development of lung cancer.
- Passive exposure to tobacco smoke also can cause lung cancer.
- The two types of lung cancer, which grow and spread differently, are small cell lung cancers (SCLC) and non-small cell lung cancers (NSCLC).
- The stage of lung cancer refers to the extent to which the cancer has spread in the body.
- Treatment of lung cancer can involve a combination of surgery, chemotherapy, and radiation therapy as well as newer experimental methods.
- The general prognosis of lung cancer is poor because doctors tend not to find the disease until it is at an advanced stage. Five-year survival is around 54% for early stage lung cancer that is localized to the lungs, but only around 4% in advanced, inoperable lung cancer.
- Smoking cessation is the most important measure that can prevent the development of lung cancer.
