In the United States 85 to 90 percent of all lung cancer cases are related to smoking. Cigarette smoking is the main cause of lung cancer (Scientific American, “Lung Cancer';). Second-hand smoke, inhaled by non-smokers, increases a person’s chance of acquiring lung cancer (Beau Halton). Men who smoke increase their chance of dying from lung cancer about 23 times and women increase their chances 13 times (“Lung Cancer Awareness Campaign,'; 3/23/99). However, lung cancer may also be caused by long term exposure to radon, a naturally present radioactive gas (SIRS, “What is Cancer?';).
Carcinogens are directly responsible for damaging DNA and causing cancer. Examples of this class of substances are radiations such as x-rays, the sun, compounds in car exhaust fumes, and the main cause for lung cancer, tobacco. According to What Is Lung Cancer?, about 87% of lung cancers are related to smoking and inhaling the carcinogens in tobacco smoke. The individuals who are affected by lung cancer may show symptoms years later, usually when the disease has already reached the advanced stage. Some symptoms include persistent or intense coughing, difficulty breathing and swallowing, hoarseness of the voice, coughing up blood, and many more.

Many of these chemicals have been proven to be cause 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.
There are however multiple causes, ways to diagnose, and treatments for lung cancer. When you think of lung cancer, you think of smoking, it is the most common cause of cancer but there are many other causes that people don’t think about. You don’t have to be a smoker to develop lung cancer, secondhand smoke, radon, diesel exhaust, air pollution, and some gene changes cause lung cancer as well. The genes that help a cell grow, divide, or stay alive are called oncogenes. The genes that slow down cell division, or cause calls to die when they are supposed to, are called tumor suppressor genes.
Exploring Lung Cancer Lung cancer is the leading cancer killer in both men and women. An estimated 169,400 new cases of lung cancer and an estimated 154,900 deaths from lung cancer will occur in the United States during 2002. There are two major types of lung cancer: non-small cell lung cancer and small cell lung cancer. Non-small cell lung cancer is much more common. It usually spreads to different parts of the body more slowly than small cell lung cancer.
There are other toxic chemicals in tobacco smoke that are suspected to cause cancer, for example: Formaldehyde, Benzo[a]pyrene, and Toluene. Smoking harms almost every organ in the human body.

LUNG CANCER: · Lung Cancer is strongly linked with smoking. · Smokers are much more likely to develop cancer.
Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. This growth may lead to metastasis to adjacent tissues and infiltration beyond the lungs. The majority of primary lung cancers are derived from epithelial cells. Lung cancer is the most common cause of cancer-related death in men and women, and is responsible for 1.3 million deaths worldwide annually, as of 2004 (37). The main types of lung cancer are small cell lung carcinoma (SCLC) and non-small cell lung carcinoma (NSCLC).
