Introduction
This patient summary on fever, sweats, and hot flashes is adapted from a summary written for health professionals by cancer experts. This and other credible information about cancer treatment, screening, prevention, supportive care, and ongoing clinical trials, is available from the National Cancer Institute. Fever is a rise in body temperature above the normal temperature. In a person who has cancer, fever may be caused by infection, a tumor, drug reactions, or blood transfusion reactions. Sweating is the body's way of decreasing body temperature by causing heat loss through the skin and, in a person who has cancer, may be associated with fever, a tumor, or cancer treatment. Hot flashes can also cause excessive sweating and may occur in natural menopause or in patients who have been treated for breast cancer or prostate cancer. This brief summary describes the causes and treatment for fever, sweats, and hot flashes.
