Lung cancer occurs primarily in persons between 
45 and 75 years of age. In the late 20th century, in 
countries with a prolonged history of cigarette 
smoking, between 80 and 90 percent of all cases of 
lung cancer were caused by cigarette smoking. 
Heavy smokers have a greater likelihood of 
developing the disease than do light smokers. The 
risk is also greater for those who started smoking 
at a young age. Passive inhalation of cigarette 
smoke is also linked to lung cancer in 
nonsmokers. In the early 1990s it was estimated 
that passive smoking caused some 2,500-3,300 
lung cancer deaths each year in the United States, 
or about 2 percent of all U.S. lung cancer deaths.
