Therefore, early detection of various symptoms and manifestations of liver cancer patients at various stages is very useful for liver cancer patients to take corresponding treatment measures in time. The so-called advanced stage of the disease often means that the disease-causing cells no longer work at the original site of occurrence, but often metastasize through various ways of metastasis. It means that the disease-carrying cells have invaded other organs and the lesions appear to be severe. It is only when the hepatobiliary tumor compresses and destroys the nerve tissues in the external envelope that the pain of hepatocellular carcinoma patients is caused. It is only when the liver tumor invades 70% of the tissue parts of the liver that the patients lose their liver functions and the tumor slowly grows and compresses the surrounding nerve tissues and organs that a series of clinical symptoms, such as indigestion and anorexia, are produced. The specific manifestations of patients with advanced liver cancer are like this. Patients will show intermittent or persistent dull pain or stabbing pain in the right upper abdomen, which is because the liver has invaded the nerve tissues of the liver envelope and then pressed the tissues and organs around the liver, resulting in blockage of other organs with blockage of blood and pain. If the liver cancer is located in the lower right lobe of the liver, a lump can be found directly under the right rib cage of the patient, while if the liver cancer is located in the left lobe of the liver, a lump can be felt under the raphe or left rib cage; due to the enlargement of the liver, the tumor invades the diaphragm and stimulates the diaphragm nerve, resulting in pain in the right shoulder. As the tumor blocks the bile duct, bile cannot be drained and accumulates in the blood, so the patient will have jaundice; loss of appetite, nausea, loss of body mass, fatigue, weakness and fever; with cancer syndrome, such as erythrocytosis and hypoglycemia.
