Liver cancer, any of several forms of disease characterized by tumours in the liver; benign liver tumours remain in the liver, whereas malignant tumours are, by deiniion, cancerous. Most malignant liver tumours are hepatomas, also called hepatocellular carcinomas (hccs). Hccs are relaively rare in the united states, accouning for between 2 and 4 percent of all cancers, but are common in other parts of the world, paricularly in sub-saharan africa, These tumours begin in the funcional cells of the liver and account for 80 to 90 percent of all liver cancers. The remaining cancers develop from blood vessels (hemangiosarcomas), small bile ducts (cholangiocarcinomas), or immature liver cells (hepatoblastomas). Treatment and prognosis for liver cancers vary, depending on the type and stage, or degree, of advancement.
