Tobacco Use and Lung Cancer
Lung Cancer
Lung cancer is the leading cancer killer among both men and women. There are two different types of lung cancer: nonsmall cell lung cancer and small cell lung cancer. There are also many different things that can cause lung cancer, but the number one cause for lung cancer is tobacco use. What is lung cancer? This is a question that a lot of people are still asking. Lung cancer is definitely something to want to be educated about so that it can be recognizable. There are healthy cells that grow and divide throughout the body to keep it functioning properly, but sometimes this growth gets out of control when the cells continue to produce even though cells aren't needed. These abnormal cells in the lungs originate when the lungs are exposed to carcinogens for instance those found in cigarette smoke. At first, only a small number of abnormal cells might appear, but as these cells are increasingly exposed to carcinogens they will definitely progress and eventually these cells become cancerous. Once these cancerous cells have reached the lungs, they have easy access to a large number of blood and lymph vessels. (MFMER 1998-2001) Cancer that begins in the lungs is divided into two major types, small cell lung cancer and nonsmall cell lung cancer. Nonsmall cell lung cancer is more common than small cell lung cancer and it generally grows and spreads more slowly. There are three main types of nonsmall cell lung cancer that are named for the type of cells in which the cancer develops. These three types are: squamous cell carcinoma, adenocarcinoma and large cell carcinoma. Squamous cell carcinoma is a cancer that forms in cells that are lining the airways. It's the most common type of lung cancer in men. Adenocarcinoma is the most common type of lung cancer in women and people who have never smoked, it is a cancer that usually begins in the mucus-producing cells of the lung. The last type of nonsmall cell lung cancer is large cell
