Risk and Associated Factors
Age Lung cancer incidence rates increase with age.
Gender The incidence is currently higher in males than in females, but the gap is narrowing due to increased smoking rates in women.
Race & SES* Generally, incidence is higher among African Americans than other racial groups and is also higher in lower income groups.
Occupation Occupational or environmental exposures to asbestos, radon, polycyclic aromatic hydrocarbons and other substances increase the risk.
Diet Diets low in consumption of fresh fruits and vegetables contribute to increased risk.
Other Cigarette smoking, including exposure to second-hand smoke, is the most important risk factor, accounting for over 85% of lung cancer deaths.

There were no cases of lung cancer among persons less than 35 years of age. The age-specific incidence rates for males were uniformly higher than the rates for females after age 54. The incidence rates increased with age, peaking in the age group 80-84 for males, and 65-69 for females. Health District 1 had statistically significantly more cases than expected based upon rates for the remainder of Idaho (p<0.01), and Health District 7 had statistically significantly fewer cases than expected (p<0.05).
