In a majority of cases, liver cancer does not doesn't have to happen if people avoid risk factors, a new global study performed in Hong Kong has found.

Simple lifestyle changes could drastically cut cases of liver cancer, according to academics. The Lancet Commission on liver cancer found that three in five liver cancer cases could be prevented by reducing alcohol consumption and obesity and by increasing uptake of the hepatitis vaccine.

Sixty percent of liver cancers are preventable by controlling risk factors including hepatitis B and C, alcohol consumption, and MASLD. The Lancet Commission estimated that a 2-5% reduction in the age-standardized incidence rate of liver cancer could prevent up to 17.3 million new cases, and save up to 15.1 million lives.
