Tumor Fever
A tumor can be a cause of fever. Sometimes the tumor results in the production of pyrogens, the chemical that induces fever. Some tumors itself can be infected. Tumors present in the brain can affect the hypothalamus, preventing it from regulating the body’s temperature, which can result in fever. Some of the drugs taken for curing fever can also result in the progression of fever. Also, the body’s immune system can be weakened in cancer, which makes the body vulnerable to infection, which can lead to fever and other disorders.
