Researchers from the American Cancer Society updated estimates of cancer-related deaths from smoking. The new numbers indicate an estimated 48.5% of the nearly 346,000 deaths from 12 cancers among adults 35 years and older were attributable to cigarette smoking.
The researchers used data from the 2011 National Health Interview Survey, the Cancer Prevention Study III, and the pooled contemporary cohort.
The results show that of an estimated 345,962 deaths, 167,805 were attributable to smoking cigarettes. Cancers of the lung, bronchus, and trachea and cancer of the larynx made up the largest proportion of smoking-attributable deaths: 80.2% and 76.6%, respectively.
In addition, approximately half of deaths from cancers of the oral cavity, esophagus, and urinary bladder were attributable to smoking.
The authors conclude that further progress in reducing cancer mortality will depend on more comprehensive tobacco control, including targeted cessation support.
