Tumor patients with recurrent fever are mainly treated with symptomatic and causative therapy including antipyretic therapy and anti-tumor therapy. Repeated fever in tumor patients is often caused by tumor. If the body temperature does not exceed 38.0 degrees, physical cooling is mainly adopted, such as applying antipyretic patches and warm water baths. If the temperature exceeds 38.0 degrees, use antipyretic drugs in time, such as diclofenac sodium, ibuprofen and so on. At the same time, anti-tumor treatment is needed, if early as possible to take radical surgery, resection with chemotherapy and radiotherapy after surgery. If surgery is not possible, chemotherapy, radiotherapy and targeted drug therapy can be carried out. Tumor patients with recurrent fever should consult the doctor in time, and cooperate with the doctor to take treatment to control the development of the disease and avoid aggravation of the disease.
