Doctor's answer (1)
Dr. Peng Xiaodong
Radiation-induced fever may result from drug-induced irritation to the body, or it may occur because the patient has relatively weak immune function, which further declines after radiotherapy, making them susceptible to bacterial, viral, or fungal infections. Additionally, when radiation reaches a certain dose, it often causes tumor tissue necrosis. As the body absorbs these necrotic tissues, inflammatory factors may be released and stimulate the body's temperature regulation center, leading to fever.
