Risk and Associated Factors
Age It is rarely diagnosed before age 50, and it is primarily a disease of older men.
Race African American males have a substantially higher rate than Caucasian males.
Genetics A family history of prostate cancer is associated with increased risk.
Diet Dietary fat has been implicated in some studies.
Occupation Persons in certain occupations are believed to be at higher risk, such as chemists, metal workers, and persons employed in the manufacture of benzidine and betanaphthylene.
Other Environmental and familial factors may contribute to an increased incidence but no specific factor in these two groups of potential risk factors has been clearly identified.

The age-specific incidence rate distribution of prostate cancer in Idaho in 1997 is similar to that reported by the National Cancer Institute’s SEER program. There were no cases of prostate cancer among persons aged less than 40 years. The age-specific incidence rates of prostate cancer increased with age, peaking in the 70-74 age group. Health District 5 had statistically significantly more cases than expected based upon rates for the remainder of Idaho (p<0.05), and Health District 7 had statistically significantly fewer cases than expected (p<0.01).
