Hara has examined 500 consequtive autopsy specimens of the colon in over 50 years of age in Japan and Matsumura has examined 121 consequtive autopsy colon specimens in Germany. The findings of the histological examinations were compared and following conclusions were obtained:<BR>1. The frequency of colonic polyps was high with increasing age.<BR>2. There was no definite difference about the frequency of colonic polyps in Japan and Germany over 50 years of age. Namely one in three to four examples over 50 years had approximately one to three tiny polyps in their colon.<BR>3. It seems that in Japan one finds polyps in the right half colon then in the left. Cancer incidence is also higher in the right half colon. The findings suggest that there could be some relationship between these two kinds of tumors of the colon.<BR>4. Diverticulosis was also examined. The frequency in Germany was four times higher than that in Japan.
