Liver cancer, also known as hepatocellular carcinoma (HCC), encompasses several types, with hepatocellular carcinoma being the most common. The main types of liver cancer include:

  1. Hepatocellular Carcinoma (HCC): HCC is the most common type of liver cancer, accounting for about 75-85% of cases. It originates from hepatocytes, the main type of liver cells. HCC is often associated with underlying liver diseases such as cirrhosis, chronic hepatitis B or C infection, excessive alcohol consumption, non-alcoholic fatty liver disease (NAFLD), and certain genetic disorders.

  2. Intrahepatic Cholangiocarcinoma (ICC): ICC arises from the bile ducts within the liver. It accounts for about 10-20% of primary liver cancers. ICC can be further classified into different subtypes based on histological features and anatomical location within the bile ducts.

  3. Hepatoblastoma: Hepatoblastoma is a rare type of liver cancer that primarily affects children under the age of 5. It originates from immature liver cells and is typically diagnosed in early childhood.

  4. Angiosarcoma and Hemangiosarcoma: These are rare types of liver cancer that develop from blood vessels within the liver. They are typically aggressive tumors and can be challenging to treat.

  5. Fibrolamellar Carcinoma: Fibrolamellar carcinoma is a rare subtype of HCC that typically affects young adults and is characterized by distinct histological and molecular features.
