Liver cancer is one of the most common nauseous tumors in China, but its early symptoms are usually not obvious, and if they are detected, most of them are in the middle and late stages of liver cancer, so it is especially important to understand the early symptoms (signs) of liver cancer to achieve early detection and early treatment so as to improve the survival rate of patients. Early symptoms of liver cancer: 1. Gastrointestinal symptoms: Significant loss of appetite, abdominal distention, indigestion, sometimes nausea and vomiting; 2. Jaundice, ascites, skin itching: About 1/3 of cases have jaundice (yellowing of skin, mucous membrane and sclera) during the course of development. Jaundice occurs because the cancer invades the major intrahepatic bile ducts and the extrahepatic bile ducts are compressed by metastatic cancer in the hilar lymph nodes. Ascites is often caused by the patient’s pre-existing cirrhosis, the invasion of cancer tissue into the veins and the formation of cancer thrombi, and the compression of the portal vein by cancer nodes. Ascites often accumulates very quickly and can be straw-yellow or blood-colored. Itchy skin is a common symptom of liver disease and hepatocellular carcinoma patients; 3. Systemic failure symptoms: severe weakness, emaciation, progressive anemia and edema; 4. Liver pain: there may be continuous or intermittent pain in the liver area, sometimes aggravated by position changes. It may radiate to the back or right shoulder. Severe abdominal pain and peritoneal irritation may occur suddenly in advanced hepatocellular carcinoma, which may be caused by necrosis of cancer nodes or bleeding into the abdominal cavity. This may be due to necrosis of cancer nodules or bleeding into the abdominal cavity. Patients often go to the emergency room with the manifestation of acute abdomen at this time; 5. Portal hypertension can cause bleeding from ruptured esophageal and gastric fundic varices. When cancerous tissues invade the bile ducts in the liver gate, it can cause biliary bleeding; 6. Hepatomegaly and splenomegaly: 90% of hepatocellular carcinoma has hepatomegaly The enlarged liver is often hard, indicating irregularity, and there can be nodules of different sizes at the edge. Giant hepatocellular carcinoma can sometimes deform the liver so that it is not easy to distinguish when palpating. Splenomegaly mostly occurs in patients with hepatocellular carcinoma combined with cirrhosis. Irregular fever: Due to the low resistance of tumor patients, it is easy to combine with infection. Some patients with liver cancer may have unexplained fever, usually around 37.5℃-38℃, or may reach 39℃ or more, which is irregular and not accompanied by chills. Fever is caused by the release of pyrogen into blood circulation after tumor tissue necrosis. Early symptoms of liver cancer are not obvious. In addition to the above symptoms, patients with early stage liver cancer may also have lower limb edema, acute abdomen and other undesirable clinical symptoms. It is suggested that patients should closely observe the vital signs, and when the above or similar conditions occur, especially those who have previously learned of hepatitis and cirrhosis, they should be alert and go to regular hospitals for necessary examination and diagnosis in time. Early detection of early symptoms of liver cancer and symptomatic treatment are the key and prerequisite to improve the efficacy of liver cancer.
