Lung cancer is one of the most common
cancers in the world and is the leading cause of cancer death in men
and women in the United States. Over 150,000 people die in the U.S.
every year from lung cancer.
Most lung cancers are caused by cigarette smoking. The more
cigarettes you smoke per day and the earlier you started smoking,
the greater the risk of lung cancer.
Second-hand smoke has also been shown
to increase risk. Government surveys show that as many as 3,000
people each year develop lung cancer from second-hand smoke. High
levels of pollution, radiation, and asbestos exposure may also
increase risk.
Lung cancer begins in cells that line
the airways and usually invades adjacent tissues or other organs
before symptoms are noticed. |
