Eliminating hepatitis B virus and hepatitis C virus could prevent 65.62% (57.47%-73.77%) and 28.47% (24.93%-32.00%) of liver cancer deaths, respectively. Achieving manageable targets in reducing the prevalence of smoking and alcohol drinking could prevent 6.57% (5.75%-7.38%) and 0.85% (0.75%-0.96%) of liver cancer deaths, with a more pronounced effect observed in males. Eliminating high body mass index (BMI) could avert 45,000 male and 25,000 female deaths annually by 2050, while diabetes elimination could prevent 60,000 male and 21,000 female deaths. Secondary prevention through liver cancer screening with 80% coverage could reduce liver cancer deaths by 3.59% (3.14%-4.04%) for the total population.

These non-tumor cells often exhibit two phenotypes with altered functions, and tumor cells drives their transition towards tumor promotion through tumor-education.
