Liver Cancer

Liver cancer or hepatic cancer is a cancer that originates in the liver. Liver cancers are malignant tumors that grow on the surface or inside the liver. Liver tumors are discovered on medical imaging equipment or present themselves symptomatically as an abdominal mass, abdominal pain, jaundice, nausea or liver dysfunction.[1] Liver cancers should not be confused with liver metastases, which are cancers that originate from organs elsewhere in the body and migrate to the liver.

There are many forms of liver cancer, although many cancers found in the liver are metastases from other tumors, frequently of the GI tract, but also from breast cancer, ovarian cancer, lung cancer, renal cancer, prostate cancer, etc.

The most frequent liver cancer is hepatocellular carcinoma (HCC) (also named hepatoma, which is a misnomer because adenomas are usually benign). This tumor also has a variant type that consists of both HCC and cholangiocarcinoma components. The cells of the bile duct coexist next to the bile ducts that drain the bile produced by the hepatocytes of the liver. Cancers which arise from the blood vessel cells in the liver are known has hemangioendotheliomas.

Hepatitis C is the primary cause of liver cancer.
