title: Cancer of the colon: a study of age-related incidence.
abstract: Incidence of colorectal cancer in Israel was studied in 1035 patients who were divided by ethno-geography into a Euro-American group and an Afro-Asian group. The majority of patients were in the age groups over 50 years, with a markedly higher incidence rate of disease in the Euro-American group. In the younger age group the incidence rate of the disease was significantly higher in the Afro-Asian group. These findings, if verified by others, must lead to revision of our present concepts of epidemiology of colorectal cancer.
