Recent advances have linked gut microbiota and bile acid alterations to this risk. This review synthesizes epidemiological evidence and molecular mechanisms, focusing on the microbiota-bile acid-FXR signaling axis, and proposes a personalized prevention framework.  \nSummary of contents Epidemiological data reveal consistent patterns: proximal colon cancer predominance, higher risk in women, and peak incidence 5–15 years post-surgery. Cholecystectomy induces gut microbiota dysbiosis (decreased Bifidobacterium breve, increased Ruminococcus gnavus) and bile acid disturbances (elevated TUDCA/ GUDCA, altered protective bile acids), which converge on FXR signaling.  \nCore findings The FXR signaling axis is a central hub. Yang et al. (Nat Commun 2025) showed that cholecystectomyinduced microbiota shifts alter bile acids, suppress FXR, disrupt FXR/β-catenin interaction, and promote tumorigenesis. The FXR agonist obeticholic acid prevents these effects preclinically, but systemic toxicity limits clinical use.  \nConclusion and significance We propose personalized risk stratification integrating demographics, microbial signatures, and metabolic biomarkers. Interventions include gut-restricted FXR agonists, probiotics, and Mediterranean diet. Future directions include prospective validation and dynamic network modeling.  \nHighlights  \n• Cholecystectomy increases proximal colon cancer risk, especially in women, with a 5–15 year latency.  \n• The gut microbiota-bile acid-FXR axis is the central mechanistic pathway.  \n• TUDCA/GUDCA are context-dependent: protective pharmacologically but FXR-suppressive after cholecystectomy.  \n• Systemic FXR agonists (OCA) have safety limitations; gut-restricted agonists are more viable.  \n• A multi-hit model explains the latency gap: cumulative DNA damage and clonal expansion over years.  \n*Correspondence: Zhongqin Huang [171076060@qq.com](171076060@qq.com)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2026.
