Quizplus · Accepted Answer

According to the National Cancer Institute, lifestyle factors (such as diet, physical activity, and weight) and environmental exposure (such as sun exposure and exposure to harmful chemicals) are associated with about 85 percent of all cancers. While genetics and related risk factors may increase an individual's risk for certain types of cancer, they are not the primary factor for the majority of cases. Tobacco use and alcohol intake are also known risk factors for several types of cancer, but they do not account for the majority of cases. Occupation-related factors may increase the risk for certain types of cancer, but they are not as widespread as lifestyle and environmental factors.
