World Liver Day is observed every April 19 and promotes global health awareness about the importance of liver health and early detection of liver diseases.

Public awareness to liver disease, liver cancer, non-alcoholic fatty liver disease (NAFLD, now known as MASLD), and hepatitis are some of the topics associated with liver health.

Worldwide, liver cancer is the sixth most common cancer, 5th most common cancer in men and 9th most common cancer in women (WCRF, 2025).
Liver cancer has accounted for up to 50% of all cancers in Africa, Southeast Asia and China.
While authorities are observing reduced rates of liver cancer in those parts of the world, liver cancer rates in North America are increasing.

Hepatitis B and C viruses are the leading cause of this cancer.
Increased rates of fatty liver disease (MASLD - metabolic dysfunction-associated steatotic liver disease), obesity and diabetes have increased liver cancer risk factors.
Widespread Hepatitis B vaccination programs have helped reduce new cases of liver cancer.
