Liver Cancer Prevention: 7 Evidence-Based Risk Reduction Strategies

While not all liver cancer is preventable, these steps significantly lower risk:

1. Limit Alcohol: Chronic abuse → cirrhosis → HCC. Abstain or drink minimally.
2. Hepatitis B/C Vaccination & Treatment: HBV vaccine (birth + series); HCV curative antivirals. Both major HCC drivers.
3. Safe Sex: Condoms reduce HBV/HCV/STI transmission.
4. Avoid Aflatoxins: Store grains/nuts properly; discard moldy food. Aflatoxin B1 = potent hepatocarcinogen.
5. Metabolic Health: Weight control, Mediterranean diet, exercise → prevent NAFLD/NASH → cirrhosis → HCC.
6. Tobacco Avoidance: Smoking independently increases HCC risk.
7. Surveillance for High-Risk: Cirrhosis, chronic HBV, genetic hemochromatosis → 6-month ultrasound ± AFP.

Early detection via surveillance improves curative treatment eligibility. Prevention starts with liver-healthy habits.
