Lung cancer occurs when abnormal cells in the lungs begin to grow and spread, sometimes throughout the body. A large group of abnormal cells in the lungs is called a tumor. Lung cancer most commonly develops in the bronchi, which is the part of the lung that divides into branches like a tree.
Lung cancer is the leading cause of cancer death in men and women in the United States. Most cases of lung cancer are caused by cigarette smoking.National Cancer Institute: Cigarette Smoking and Cancer Prize winner author John Updike died of lung cancer on January 27, 2009.KTAR (Arizona): John Updike, Prize-Winning Writer, Dead at Age 76 (January 27, 2009)
Types
There are two main categories of lung cancer: small cell lung cancer and non small cell lung cancer. Non-small cell lung cancer is the more common of the two types.Distinguishable by cell size, small cell lung cancer accounts for only about 10 to 15% of lung cancer cases. The cancerous cells spread quickly, nearly always requiring a drug-based treatment. The more common varieties are considered non-small cell lung cancer and typically develop over a period of years.American Cancer Society: What Is Small Cell Lung Cancer?
Causes
Some genetic traits can also make some people more susceptible to cancer-causing substances than others. Aside from the chemicals found in cigarettes, other cancer-causing substances include asbestos, silica, mineral dusts, coal dust, radioactive gas, radon, and arsenic.-
