Lung cancer is the most common cause of death due to cancer in both men and women throughout the world. Statistics from the American Cancer Society estimated that in 2016 about 224,000 new cases of lung cancer in the U.S. occurred. According to the U.S. National Cancer Institute, approximately 6.5% of men and women in the U.S. will be diagnosed with cancer of the lung at some point in their lifetime based on data from 2011-13.
1) Cigarette smoking is the main risk factor for development of lung cancer.
2) Passive exposure to tobacco smoke also can cause lung cancer.
3) The two types of lung cancer, which grow and spread differently, are Small Cell Lung Cancers (SCLC) and Non-Small Cell Lung Cancers (NSCLC).
4) The stage of lung cancer refers to the extent to which the cancer has spread in the body.
5) Treatment of lung cancer can involve a combination of surgery, chemotherapy, targeted therapy, immunotherapy, and radiation therapy as well as newer experimental methods.
6) 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.
7) Smoking is the most vital measure that can prevent the development of lung cancer.
