*
Cigarette smoking causes 87 percent of lung cancer deaths and is responsible for most cancers of the larynx, oral cavity and pharynx, esophagus, and bladder (see Question 1).
*
Secondhand smoke is responsible for an estimated 3,000 lung cancer deaths among U.S. nonsmokers each year (see Question 2).
*
Tobacco smoke contains thousands of chemical agents, including over 60 substances that are known to cause cancer (see Question 3).
*
The risk of developing smoking-related cancers, as well as noncancerous diseases, increases with total lifetime exposure to cigarette smoke (see Question 4).
*
Smoking cessation has major and immediate health benefits, including decreasing the risk of lung and other cancers, heart attack, stroke, and chronic lung disease (see Question 5).

Tobacco use, particularly cigarette smoking, is the single most preventable
cause of death in the United States. Cigarette smoking alone is directly
responsible for approximately 30 percent of all cancer deaths annually in
the United States (1). Cigarette smoking also causes chronic lung disease
(emphysema and chronic bronchitis), cardiovascular disease, stroke, and
cataracts. Smoking during pregnancy can cause stillbirth, low birthweight,
Sudden Infant Death Syndrome (SIDS), and other serious pregnancy complications
(2). Quitting smoking greatly reduces a person’s risk of developing the
diseases mentioned, and can limit adverse health effects on the
developing child.
