Cancer
Many cancers can cause an elevation of the body’s temperature due to:
- Increased body metabolism owing to the rapid uncontrolled division of cancer cells.
- As a result of cancer cell destruction by chemotherapy or radiotherapy which results in the release of chemical inflammatory mediators that induce fever.
- Paraneoplastic syndrome: paraneoplastic syndrome comprises a group of symptoms not related to the cancer itself, rather the result of the release of hormones or chemical mediators by cancer cells. Among these hormones are those that raise body temperature, blood pressure, or cause gastrointestinal side effects like diarrhea and cramping.
