Moreover,
Number liver cancers could double:
Better vaccination coverage against hepatitis B and policies targeting obesity and alcohol consumption are necessary for lower the number of liver cancerssays an international study published in The Lancet Tuesday July 29, 2025.
That’s not all: according to this same study. Meanwhile, due to the lack of public action, the number of cases of the most frequent sixth cancer (and the third deadliest) could have almost doubled around the world in 2050.
Avoidable risk factors – Number liver cancers could double
According to researchers. Consequently, Three in five liver cancers are due to avoidable risk factors on which it should be actful: viral hepatitis, alcohol consumption and non -alcoholic hepatic steatosis (characterized by an accumulation of number liver cancers could double fat in the liver, often associated with obesity).
Viruses hepatitis B and C should remain the main causes of liver cancer in 2050, while seeing their share decrease (36.9% of cases against 39% for the first, 25.9% against 29.1% for the second).
While vaccination against hepatitis B is the most effective means of prevention. “coverage remains low in Africa and in low -resources regions” because of its “cost, reluctance to be vaccinated and the ignorance of its effectiveness” and for lack of vaccination obligation, says the study.
The share of liver cancers due to the alcohol consumption And to steatosis should increase: the accumulation of fat in the liver will be involved in 11% of cases in 2050 (compared to 8% in 2022). an increase of 35%, and alcohol, of 21.1% of cases on this horizon, according to their calculations.
1.52 million new cases per year
The works carried out by a commission of experts from six countries (China. United States, South Korea, Italy, Spain and France, where Inserm has collaborated in particular) also underlines “the urgency of global action” against liver cancer, after having screened the studies and available data.
According to the World Cancer Observatory, on the planet’s scale in 2050 the number of new cases will climb to 1.52 million per yearor almost doubly. 1.37 million people will die.
Eight out of 10 of these cancers are hepatocellular carcinomas. a particularly present form in East Asia, North Africa and Southeast Asia. Globally, the patient’s survival rate at five was 5% to 30% between 2000 and 2014.
