This study was designed to evaluate the effects of Chrysin in combination with 5-FU on azoxymethane (AOM) - induced colon cancer in mice. Materials and Methods: In this study 42 male balb/c mice weighing 15-18 g, were used. Mice were divided into seven groups: 1) Health control, 2) Cancer Control, 3) 5-FU,   4) Chrysin with dose of 50 mg/kg, 5) Chrysin with dose of 100 mg/kg, 6) Chrysin with dose of 50 mg/kg plus 5-FU, 7) Chrysin with dose of 100 mg/kg plus 5-FU. Colon cancer was induced by i.p. infusion of AOM (10mg/kg) and (Dextran sodium sulfate) DSS (1.5%) in the drinking water for one week.  All rats were sacrificed for evaluation of histopathology (hyperplasia, dysplasia, carcinoma and the number of aberrant crypt foci ,ACF)  in distal region of large intestine. Results: Pathological lesions (hyperplasia, dysplasia and carcinoma) and the number of aberrant crypt foci (ACF) was lower in all treatment groups compared to the cancer control group (p CP - IRAN IN - 5.
