[0002] Radiotherapy is a medical treatment method that uses radiation to irradiate the patient's tumor or lesion to achieve the therapeutic effect of killing cancer cells or diseased cells, reducing tumor volume, relieving symptoms or preventing recurrence. Radiation can directly damage the DNA structure of cells, causing cancer cells to lose their ability to grow and eventually die. Radiotherapy is usually used as part of cancer treatment. It can be used alone or in combination with other treatments such as surgery and chemotherapy. A personalized treatment plan is developed based on the patient's specific situation and cancer type. Radiotherapy requires treatment with specialized radiotherapy equipment.
