Lung cancer is the number one cancer killer of both men and women in the
United States. The first Surgeon General’s Report on smoking and health in
1964 found that smoking was a cause of lung cancer in men. Since that time,
risks for developing lung cancer have risen steadily among smokers, and
have risen dramatically among women smokers. Changes in the design and
contents of cigarettes over the last 50 years have contributed to higher lung
cancer risks among smokers.
