quote: Each year, primarily because of exposure to secondhand smoke , an estimated 3,000 nonsmoking Americans die of lung cancer
quote: In the United States, smoking is estimated to account for 87% of lung cancer
quote: 10–15% of lung cancer patients have never smoked. That means between 20,000 to 30,000 never-smokers are diagnosed with lung cancer in the United States each year. Because of the five-year survival rate, each year in the U.S. more never-smokers die of lung cancer than do patients of leukemia, ovarian cancer, or AIDS.
