放射治疗
(medicine) the treatment of diseases like cancer using radiation from a radioactive source
Irradiation refers to the use of high-energy radiation, such as X-rays or gamma rays, to target and treat tumors or abnormal cells in the body. This form of treatment is commonly used in radiation therapy, where radiation is directed precisely at cancerous tissues to destroy or shrink them. Irradiation works by damaging the DNA within cancer cells, preventing them from dividing and growing further. It is done by trained healthcare professionals in controlled doses to minimize damage to healthy surrounding tissues. Irradiation is an essential part of cancer treatment, often used in combination with surgery and chemotherapy to achieve the best possible outcome for patients.
