Overall, this estimate found that 40% of all incident cancers among adults age 30+ living in the U.S. could have been prevented, as well as 44% of cancer deaths. Cigarette smoking remains the largest single cause of cancer incidence and death, and is responsible for 19.3% of cases and 28.5% of cancer deaths. Excess body weight, only somewhat recently recognized as a risk factor for cancer, was responsible for the 2nd largest cause of cancer incidence and death, with a population attributable fraction of 7.6% and 7.3% of cases and deaths, respectively.
