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.
- HCC is more frequently found in Africa and Asia than in other parts of the world. It is uncommon in the United States. The most common causes and risk factors of hepatocellular carcinoma are:

- Chronic hepatitis B or the hepatitis C virus infection
- Excessive alcohol consumption
- Certain inherited liver diseases. Such as hemochromatosis, Wilson's disease, etc.
- Some toxins and chemicals. Such as Aflatoxin, which is a toxin from a type of fungus that often found in wheat, soybeans, peanuts, corn, and rice in certain area of the world; Arsenic, which is toxic chemical; etc.
- Anabolic steroids
