Liver cancer is a cancer that develops in the cells of your liver. Your liver is an organ that is similar to a football in size and located in the upper right part of your abdomen, below your diaphragm and above your stomach.
Several types of cancer can occur in the liver. The most common type of liver cancer is hepatocellular carcinoma, which begins in the main liver cell (hepatocyte). Other types of liver cancer, such as intrahepatic cholangiocarcinoma and hepatoblastoma, are less common.
Not all cancers affecting the liver are considered liver cancer. If cancer begins in another area of the body – such as colon, lung or breast – and spreads to the liver, it is called metastatic cancer rather than liver cancer. This type of cancer is named after the organ where it originates – like metastatic colon cancer to identify cancer that developed in the colon and spread to the liver. Cancer that spread to the liver is more common than cancer that develops in the hepatic cells.
