Hepatic s5 metastasis is a metastatic malignant tumor in the fifth segment of the liver. The liver is divided into eight segments based on the distribution of the hepatic vein and portal vein within the liver. Liver metastases are mainly malignant tumors in other parts of the body. As tumor cells break through the endothelium of blood vessels to enter the bloodstream, they can stay in the blood vessels of the fifth segment of the liver as they pass through the liver and invade the hepatocytes to grow new malignant tumors. Metastatic tumor of the fifth segment of the liver is usually in advanced stage when it is detected. In addition to the symptoms of the primary tumor, it may also be accompanied by pain in the upper abdomen or liver area, fatigue, weight loss, loss of appetite, ascites and other symptoms. The occurrence of segment V metastatic tumor of liver needs to go to the hospital for examination and treatment in time to avoid delaying the condition.
