Introduction
Common side effects of radiotherapy include systemic reactions such as fatigue, insomnia, decreased appetite, nausea, and vomiting, as well as local symptoms. Patients receiving cranial irradiation may develop cerebral edema or radiation-induced injuries, including radiation ulcers, spinal cord necrosis, bone necrosis, and brainstem necrosis. Long-term toxicities associated with radiotherapy include the development of secondary primary malignancies and infertility.
Radiotherapy is a medical discipline focused on the study and clinical application of ionizing radiation—either from radioactive substances or external radiation sources—for the treatment of tumors. Although radiotherapy is primarily a local treatment modality, it serves as a vital component of comprehensive cancer management and has broad clinical applicability. While effectively killing tumor cells, radiotherapy inevitably produces certain adverse effects. Common side effects include systemic reactions such as fatigue, insomnia, loss of appetite, nausea, and vomiting, as well as localized symptoms.
Patients undergoing cranial irradiation may develop complications such as cerebral edema or radiation-induced injuries—including radiation ulcers, spinal cord necrosis, bone necrosis, and brainstem necrosis—which must be carefully avoided. Long-term toxicities associated with radiotherapy include the development of secondary primary malignancies and infertility. Therefore, appropriate protective measures must be implemented for patients undergoing radiotherapy to minimize adverse effects and prevent further harm.
