When you think of tumors, you will immediately think of cancer, and there is a misconception here that not all tumors are malignant. Still, let’s first understand what are the common liver tumors and the basic knowledge we need to know about liver tumors. Liver tumors are classified as primary and secondary. Primary liver tumors are divided into malignant and benign. Primary malignant liver tumors are divided into hepatocellular carcinoma derived from hepatocytes, cholangiocellular carcinoma derived from bile duct epithelium and mixed hepatocellular carcinoma derived from both, among which hepatocellular carcinoma derived from hepatocytes is the main type; primary benign liver tumors are mostly seen as hemangioma and cystic disease. Secondary liver tumors are malignant and are metastases from other organs to the liver or secondary intrahepatic metastases, so they are also called metastatic liver cancer. Clinical manifestations Hepatomegaly and epigastric mass are characteristic signs of middle and late stage hepatocellular carcinoma. Those with advanced hepatocellular carcinoma or background of hepatic sclerosis may have jaundice, ascites, splenomegaly, swelling of lower limbs, liver palm, spider nevus and abdominal wall varices at the same time. 1.hepatomegaly located in the upper right lobe of the liver is manifested by the upward shift of the upper border of the liver, diaphragm elevation, fixation and limitation of movement; the lower right lobe of the liver can often be palpated as a mass under the right costal arch; the left lobe of the liver is often manifested as a mass under the saber, or with an upper abdominal bulge. The texture of the enlarged liver is usually hard; if necrosis and liquefaction or intra-tumor bleeding occur, the texture becomes soft or cystic in nature. 2. Ascites is a physical sign of advanced liver cancer. If it is caused by hepatic vein or portal vein obstruction, it is hypertonic ascites, which is characterized by rapid growth of ascites, drumming sound on percussion of abdomen and full abdominal bulge. If caused by hepatic sclerosis, the tension is lower. In cases with hepatic or inferior vena cava obstruction or hypoproteinemia, it may be accompanied by lower limb edema. In the case of ruptured hepatocellular carcinoma nodules combined with ascites, it is often bloody and accompanied by abdominal pressure pain. If it is caused by cancer invading the peritoneum, it is cancerous ascites. If the amount of ascites is high or right subdiaphragmatic liver cancer, there may be right pleural fluid. 3.Jaundice, which is yellowish color of sclera or brush skin, is an advanced sign of hepatocellular carcinoma. It is mostly caused by direct compression of cancer or invasion of bile duct and common bile duct, or damage of hepatocytes.
