Patients with throat cancer may develop a fever because the tumor can secrete pyrogens. If pyrogens are released into the bloodstream, they can cause a fever. Another scenario is that throat cancer is accompanied by bacterial or fungal infections, which can also lead to a fever. If the fever is caused by the tumor, using antibiotics alone will not be effective. It is recommended that the patient undergoes active anti-tumor treatment. By effectively controlling the tumor, the body temperature will generally return to normal. If the fever is due to a concurrent infection, anti-inflammatory treatment is advised to effectively control the infection, and the body temperature will gradually return to normal. Therefore, if a patient experiences a fever, it is important to first determine the cause of the fever and then proceed with targeted treatment. Generally, the body temperature will slowly return to normal after treatment.
