A Tukey's post hoc test revealed that the percent small (< 5 mm2) neoplasms was lower in mice fed a Western diet without supplements (42.3 ± 10.6%) compared to the percent small neoplasms in mice fed a control with a propolis supplement (64.8 ± 8.2%, P = 0.030) (W vs. CP, Fig. 2A). This evidence concerns the gene CP and neoplasm.
