Risk and Associated Factors
Age Rates increase with age.
Gender Incidence rates for males are usually more than twice as high as for females.
Race & SES* There is a higher incidence in African Americans, as well as Asians, and incidence is also higher in lower income groups.
Diet Increased risk has been attributed to diets high in smoked foods and foods high in nitrates. Diets high in fresh fruits and vegetables seem to be protective.
Occupation Elevated rates have been found in certain occupatonal groups, especially coal miners and asbestos workers.
Other Stomach cancer has recently been linked to peptic ulcer disease and to certain bacteria associated with increased risk for both diseases.

There were no cases of rectal cancer among persons aged less than 25 years. The age-specific incidence rates of rectal cancer generally increased with age, peaking in the 85+ age group for males and 70-74 age group for females. No health districts had significantly more cases than expected based upon rates for the remainder of Idaho.
