This chapter examines the relationship between marital status and the incidence of cancer of the rectum among white and African-American males. Incident cases of rectal cancer were abstracted from the Third National Cancer Survey data and classified by gender, age, and marital status for whites and African-Americans for ages ranging from thirty-five to sixty-four years. The results from the median polish approach show that widowed men have the highest estimated rate of rectal cancer, followed by single men. The lowest estimated rates are observed in married men. Blacks have lower estimated rates than whites in the age categories forty-fve–fifty-four and fifty-five–sixty-four. The parametric model gives somewhat different results. The highest estimated cancer rates are found among single men, followed by widowed men. The lowest estimated rates are found in men from separated couples. Whites and blacks have almost identical estimated rectal cancer incidence rates within each of the three age categories.
