One-Third of U.S. Cancer Deaths Due to Cigarette Smoking, Study Finds

Cigarette smoking causes about three in 10 cancer deaths in the United States, according to a new study by researchers at the American Cancer Society. The estimate does not include deaths from secondhand smoke.

The researchers also excluded deaths due to other types of tobacco including cigars, pipes and smokeless tobacco, HealthDay reports. The findings are published in Annals of Epidemiology.

The study is the first in more than 30 years to estimate the percentage of cancer deaths in the United States that are due to smoking, the researchers said. The previous study also found 30 percent of U.S. cancer deaths were caused by smoking. Since then, smoking rates have dropped, but new cancers have been added to the list of those established as caused by smoking, the researchers said. In addition, lung cancer death rates among female smokers have risen.
