The possible pathway of early-onset colorectal cancer (EOCRC). Inflammatory diet (high fat and sugar diet), endogenous N-nitroso compound (NOC), polycyclic aromatic hydrocarbons (PAH), heterocyclic amines (HCA), heme, stress, F. nucleatum and B. fragilis toxin (BFT), produced by enterotoxigenic B. fragilis (ETBF), induced inflammation through stimulation of inflammatory cytokines and causes (i) the activation of β-catenin and STAT3 signaling pathway; and the activation of transforming growth factor beta 1 (TGFB1) pathway (Nakamura et al., 2019).
