Hypoglycemia: The liver itself has a strong compensatory capacity, and only when the area of liver damage exceeds 70% to 80%, obvious hypoglycemia will appear, manifesting as dizziness, weakness, false sweating and other symptoms. Erythrocytosis: Patients with long-term cirrhosis or chronic liver disease with no other reason for increased red blood cells may be an early sign of liver cancer and should be given great attention. This is because, when cancer cells in liver divide, they produce a lot of erythropoietin, resulting in excessive erythropoiesis. However, the increase in red blood cells in liver cancer patients is not accompanied by an increase in white blood cells, platelets and lymphocytes. Therefore, a higher erythrocyte count indicates a more vigorous cell division in hepatocellular carcinoma. Clinical manifestations include red face and polycythemia physical appearance. Hyperlipidemia: Patients with cirrhosis and chronic hepatitis who have excluded high-fat diet, heavy alcohol consumption, lack of exercise and certain endocrine diseases, but still have hyperlipidemia, are also considered as a sign of liver cancer. The clinical signs and symptoms of hyperlipidemia, such as obesity and atherosclerosis, are manifested. Hepatic hemangioma: Hepatic hemangioma and hepatocellular carcinoma are easily confused. In fact, hemangioma grows slowly and usually has no history of chronic liver disease, no clinical manifestations such as weakness, poor appetite and abdominal distension, and no signs such as liver palms, spider nevus, jaundice and bilateral lower limb edema. Uneven fatty liver: Some patients with fatty liver have uneven fat accumulation, which is sometimes difficult to distinguish from liver cancer. Clinically, fatty liver will not have the systemic manifestations of liver cancer patients, such as abdominal distension, diarrhea, discomfort in the right side of liver area, and wasting.
