What are the early symptoms of liver cancer? Digestive tract symptoms:Decreased appetite, fullness in the upper abdomen after meals. Ambiguity, indigestion and nausea are common digestive symptoms of liver cancer, among which loss of appetite and bloating are the most common. Diarrhea is also a more common digestive symptom of liver cancer, which has been reported both at home and abroad, with high incidence and easily mistaken as chronic enteritis. Portal hypertension and intestinal dysfunction caused by thrombosis of portal vein or hepatic vein can lead to abdominal distension and increased frequency of bowel movement, and abdominal distension can also be caused by ascites. Gastrointestinal dysfunction can also lead to indigestion, ambiguity, nausea and other symptoms. Wasting and fatigue:Patients with hepatocellular carcinoma often feel more fatigue than patients with other tumors, which is similar to patients with chronic hepatitis. The cause of fatigue is unknown, which may be due to digestive disorders, nutrient absorption obstacles leading to insufficient energy, or damaged liver cells and decreased liver function, resulting in metabolic disorders, certain toxins can not be inactivated in time, or toxic substances are released by necrosis of liver cancer tissues. Wasting is also a common symptom of liver cancer patients, which is due to impaired liver function. It is due to the damage of liver function and the decline of digestion and absorption function. With the development of disease, the degree of emaciation can be aggravated, and in serious cases, malignant lower limb edema can be seen: patients with ascites in liver cancer often have lower limb edema, which occurs in the ankle in mild cases, and spreads to the whole lower limb in serious cases. Clinically, some patients have been seen to have high edema of lower limbs, and the fluid can ooze out from the skin of thighs. The main cause of lower extremity edema is ascites compression of lower extremity veins or obstruction of cancer thrombus, which obstructs venous return. Mild edema can also be caused by low plasma albumin Fever:A considerable number of patients with hepatocellular carcinoma will have sweating and fever. Most of the fever is medium-low fever, and a few patients may have high fever above 39℃, which is usually not accompanied by chills. Fever of liver cancer is mostly cancerous fever, which is caused by the release of pyrogen into blood circulation after necrosis of tumor tissues. Due to the low resistance of tumor patients, they may easily be infected and have fever, which is not easy to be distinguished from the cancer fever of liver cancer, and it needs to be determined by combining with the blood picture and observing whether the antibacterial treatment is effective or not.
