Risk and Associated Factors
Age Rates usually increase steadily with age. Most cases are adults in mid-life or older.
Gender Males have a higher incidence than females for most cancer types.
Race & SES* Rates are higher for African Americans than for Caucasians and other ethnic groups.
Rates are generally higher among lower income groups.
Occupation Risk for cancer is greater with some kinds of workplace exposure, such as chemicals, asbestos, and radiation.
Diet Diets that are low in fresh fruits and vegetables have been associated with increased incidence of several cancers.
Other Tobacco use is the single most important risk factor for cancer incidence and mortality.

The incidence rates for all cancers combined were similar for males and females in Idaho until approximately age 60-64, after which rates for males rose dramatically. The highest rates for both males and females were observed in age groups after age 70, peaking in the age group 70-74 for males and 80-84 for females. Health Districts 1 and 4 had statistically significantly more cases of cancer than expected based upon rates for the remainder of Idaho (p<0.01), and Health District 3 had statistically significantly fewer cases than expected (p<0.01).
