The liver is an organ that has a size as big as a football located at the upper right area of the abdomen just above the stomach and below the diaphragm. Liver cancer begins at the liver cells (hepatocytes). The most common type of liver cancer is hepatocellular carcinoma that mainly affects the hepatocytes. There are other types of liver cancer which are rare such as intrahepatic cholangiocarcinoma and hepatoblastoma.
Cancers that originate from other parts of the body (e.g. breast, lung or colon cancer) can spread to the liver. This is called metastatic cancer.
Signs and symptoms mostly not show when primary liver cancer is in its early stage.

The cause of liver cancer may be known such as having chronic infection with hepatitis. However, the cause is sometimes unknown if there are no underlying conditions which may have resulted in liver cancer.
These are the factors which may develop into primary liver cancer:
