What is the most common malignant mass of the liver?

Hepatocellular carcinoma is the most common primary malignant tumor arising in the liver. It typically develops in the setting of cirrhosis or chronic hepatitis B or C, where ongoing liver injury and regeneration promote malignant transformation of hepatocytes. This makes it more prevalent than other primary liver cancers such as cholangiocarcinoma (bile duct cancer) and angiosarcoma (a rare vascular tumor). It’s also helpful to note that while metastases to the liver are the most frequent malignant liver involvement overall, those cancers originated elsewhere and merely spread to the liver rather than starting there. So, for a malignant mass that begins in the liver tissue itself, hepatocellular carcinoma is the best answer.
