Types of Liver Cancer
on the cells or tissues affected, liver cancer is classified into several groups:
carcinoma - this type of
cancer develops in a group of liver cells called hepatocytes. Hepatocellular carcinoma is the common type
of primary liver cancer, and it is mostly due to complication of a disease already existed in the liver
- also called bile duct cancer,
cholangiocarcinoma develops in the ducts of the liver that carry bile to the small intestine. It can
cause biliary obstruction (bile duct obstruction), hence emergence of cholestasis syndrome.
- also known as hemangiosarcoma,
angiosarcoma is a rare form of cancer that starts in blood vessels of the liver. It is often caused by
prolonged exposure to toxic metals.
– although hepatoblastoma is a rare
form of primary liver cancer, it is the most common type of liver cancer in children. It is characterized
by a palpable liver mass and abdominal pain. Hepatoblastoma represents approximately 1% of all pediatric
tumors with an annual incidence of 1.5 cases per million children younger than 4 years.
