Scientists at World Cancer Research Fund examined numerous studies involving 8.2 million people also determined that having more than three alcoholic drinks poses an increased risk of causing liver cancer.
Amanda McLean, Director of World Cancer Research Fund UK, said: “Around three or more drinks per day can be enough to cause liver cancer. Until now we were uncertain about the amount of alcohol likely to lead to liver cancer. But the research reviewed in this report is strong enough, for the first time, to be more specific about this.”
However, alcohol is not the only one causing liver cancer. Other causes include being overweight or obese, or consuming food contaminated with aflatoxins – toxins produced in certain fungi.
The report containing the findings is the most comprehensive review of global research to date into the relationship between diet, physical activity, and liver cancer. It contains recommendations for women to try limiting the alcohol intake to one drink per day, while per are urged to have two drinks per day at most.
Other recommendations in the report suggest being as lean as possible without becoming underweight and carrying out physical activity for at least 30 minutes every day.
Liver cancer is one of the most deadly cancers with just a 12% survival rate after five years.
Around 4,700 people are diagnosed every year in the UK but nearly a quarter of cases diagnosed in the UK could be prevented if people kept a healthy weight and did not drink, the charity said.
