Liver Cancer

Liver cancer is diagnosed in an estimated 42,000 people each year, primarily in men, and results in over 42,000 annual deaths in the United States. The liver is more often a site of metastases rather than the origin of cancer; however, there are several types of cancer that begin in the liver. Hepatocellular Carcinoma (HCC) is the most common type of liver cancer, causing nearly three-quarters of cases. Bile Duct Cancer, or Cholangiocarcinoma, represents 10% to 20% of cases and occurs in the bile duct. Angiosarcoma grows rapidly within the liver’s blood vessels; however, only about 1% of liver cancer is classified as Angiosarcoma.
