      Abstract: The visualization of induced colonic   tumors in rats was investigated using either a rigid or flexible   endoscope. There was 89% agreement between presence or absence of   at least one tumor as visualized at endoscopy and necropsy. The   agreement was 83% (p < 0.01) when the exact number of tumors   was compared. Neither carcinogens (1,2-dimethylhydrazine or   N-methylnitrosourea) nor dietary supplements affected the   results.
