Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world as of 2004.

Hepatocellular carcinoma is much more common outside the United States, representing 10% to 50% of malignancies in Africa and parts of Asia.

There is no such thing as "hepacocllulan carcinoma", but hepatocellular carcinoma is a cancer of the liver associated with viral hepatitis, poisonous mushroom ingestion, and fungal toxins.

Yes, "hepatic liver cancer" and "hepatocellular carcinoma (HCC) of the liver" are referring to the same condition. Hepatocellular carcinoma is the most common type of primary liver cancer, and it specifically refers to cancer that begins in the hepatocytes, which are the main type of liver cells. "Hepatic" simply means "related to the liver," so "hepatic liver cancer" is another way to describe hepatocellular carcinoma or liver cancer that originates in the liver cells.
