Liver cancer patients may have fever, liver muscle pain, abdominal distention, nausea, vomiting, and jaundice. When the patient has fever, first rule out whether there is infection. If the fever is caused by infection, select sensitive antibiotics for anti infection treatment. If the infection is excluded and the fever caused by the tumor itself is eliminated, some antipyretic and analgesic drugs can be selected to reduce the fever by physical cooling. The patients with liver cancer should be actively treated. The appropriate scheme can be selected according to the tumor stage of the patient, including surgical intervention, radiotherapy, chemotherapy, immediate treatment, etc. Usually, after treatment, it can improve the survival rate of patients and prolong their life.
