Is primary liver cancer benign or malignant?

Primary liver cancer is a malignant tumor, not a benign tumor.

Pathologically, primary liver cancer is usually divided into three types: hepatocellular carcinoma, intrahepatic cholangiocarcinoma and extrahepatic cholangiocarcinoma. Hepatocellular carcinoma is more common, originating from liver cells, usually developed on the basis of liver diseases such as hepatitis and cirrhosis. Intrahepatic cholangiocarcinoma is rare, originating from intrahepatic cholangioepithelial cells, most of which are related to bile duct stones and inflammation. Extrahepatic cholangiocarcinoma is more rare. It originates from epithelial cells of extrahepatic bile duct and may be caused by biliary stricture, cholangitis and other diseases.

Primary liver cancer has the characteristics of unlimited proliferation, migration and invasion of tissues, and is easy to spread to other organs. Therefore, early detection and early treatment are recommended. Treatment methods include surgery, radiotherapy and chemotherapy.
