Liver cancer patients experiencing a fever of 38°C can be seen in the following scenarios: The first type is tumor-related fever. In liver cancer patients, especially those in the advanced stages or with large tumors, a fever of around 38°C can occur in the absence of infection symptoms. This tumor fever is related to various mediators released into the blood by the tumor. The second type is infectious fever. Cancer patients undergoing anti-tumor treatment may experience immunosuppression and concurrent infections. This type of fever often exceeds 38.5°C but can also occur around 38°C in the early stages, often accompanied by symptoms of infection such as coughing, sputum production, abdominal pain, and diarrhea. The third type is treatment-related fever. Patients with liver cancer may experience a fever of around 38°C on the day of and several days following interventional treatments.
