Family History of Liver Cancer

A person’s risk of developing liver cancer increases if they have a family history of liver cancer. In a study conducted in the United States, people who had a parent, sibling, or child with liver cancer were about four times more likely to develop liver cancer than individuals without such a family history. This increased risk was seen even among people without viral hepatitis. This study suggests that either genetic factors or shared environmental factors influence the risk of liver cancer. People with hepatitis B or hepatitis C infection who also had a family history of liver cancer were at the highest risk of developing liver cancer, especially at a young age.
