Singapore Study Finds Fatty Liver Gene Raises Liver Cancer Risk 9-Fold in Obese Men
5 articles · Updated · The Straits Times · May 26
Nearly 25,000 participants in the Singapore Chinese Health Study showed a fatty-liver genetic variant, combined with diabetes and obesity, sharply increased hepatocellular carcinoma risk.
Men with visceral fat — the so-called beer gut — faced up to 9 times higher risk, and the genetic link appeared stronger in people without chronic hepatitis B.
Researchers said current screening typically assesses fatty liver or metabolic disease separately, but the findings support combining genetic data with routine checks such as diabetes, cholesterol and weight for targeted monitoring.
Liver cancer ranked among the top 3 causes of male cancer deaths in Singapore in 2019-2023, and researchers say non-viral causes such as fatty liver disease are becoming more important as the cancer often shows no early symptoms.
A follow-up study has recruited about 170 of a planned 200 liver cancer patients and relatives, aiming to refine earlier detection after one participant's 2025 research scan found an unrelated early-stage tumour.

Your genes can raise your liver cancer risk, but can lifestyle changes rewrite that destiny?
Genetic and Metabolic Stacking Drives Surge in Non-Viral Liver Cancer: Insights from the 2026 Singapore Study
Overview
A groundbreaking Singapore study published in May 2026 has transformed our understanding of liver cancer by revealing a major shift from viral to non-viral causes, such as fatty liver disease and metabolic conditions. The research highlights that genetic predispositions, especially the PNPLA3 I148M variant, play a crucial role in increasing liver cancer risk, particularly when combined with obesity or diabetes. This synergy means that genetic and metabolic factors together dramatically raise the risk of hepatocellular carcinoma. The findings underscore the urgent need for integrated screening and prevention strategies that consider both genetic and metabolic health.
