Cigarette smoking played a role in 19% of cancers and 29% of cancer-related deaths in 2014.
It is well-known that certain modifiable risk factors—including diet and smoking—can prevent the development of cancer. New data published by CA: A Cancer Journal of Clinicians suggests that nearly half of cancer cases and cancer-related deaths are preventable.
Based on current cancer rates, the authors estimated that 42% of cancer cases and 45% of cancer deaths are associated with modifiable risk factors.
In 2014 specifically, 659,640 out of 1.6 million cancer cases and 265,150 out of 587,521 cancer deaths were preventable, according to the study.
The authors calculated how much modifiable lifestyle behaviors contributed to the risk of 26 different cancers among adults 30 years of age and older. Risk factors included:
