What are the differences between hepatoma and hepatocellular carcinoma?

No difference: Hepatocellular carcinoma, cancer of the liver, is referred to by some doctors as "hepatoma". The term "hepatoma" is misleading to some patients because it does not sound the medical terms used to describe other malignant tumors (for instance, "squamous cell carcinoma" or "adenocarcinoma") and could easily be mistaken for a benign diagnosis.

They are the same: Hepatoma and hepatocellular carcinoma are terms used interchangably to describe the same diagnosis, hence the treatment and prognosis are the same.

They are the same: Hepatoma is hepatocelluar carcinoma and represents a primary tumor of the liver. It is most commonly seen in patients with underlying liver disease, like hepatitis.

There are none: The current preferred term for primary liver cancer is hepatocellular carcinoma; hepatoma is an older term for the same disease.
