Liver Cancer

Liver cancer ranks number 3 in cancer caused death world wide. Liver cancer is the growth of cancer in the liver. If the cancer is from liver cells, it is called hepatocellular carcinoma (HCC), which accounts for the most of the liver cancers. Cancer grows from the bile duct is called cholangiocarcinoma. If the cancer is from somewhere outside of the liver, but migrates into the liver, it is called metastatic liver cancer, which can be colon cancer, lung cancer, pancreatic cancer, etc. Here, we mainly discuss about HCC.
