Background technique

Radiotherapy is a medical term and is one of the three major treatment methods for cancer. It irradiates the tumor with rays of various energies to inhibit and kill cancer cells. Radiotherapy can be used alone or in combination with surgery, chemotherapy, etc., as part of comprehensive treatment to improve the cure rate of cancer. Malignant tumors can be histologically divided into two categories: one is called carcinoma, which is caused by malignant transformation of epithelial cells. For example, lung epithelial cells undergo malignant transformation to form lung cancer. The malignant transformation of leaf tissue is called sarcoma, such as leiomyosarcoma, fibrosarcoma, etc. People hear more about cancer and less about sarcoma, which is related to the fact that there are far more cancer patients than sarcoma patients. Clinically, the ratio of carcinoma to sarcoma is approximately 9:1. Cancer is a type of malignant tumor that evolves from normal cells in the human body. When normal cells become cancerous, like a wild horse, the body cannot restrain it, resulting in so-called "dysplasia." Dysplasia is relative to normal proliferation of cells. Human cells have a process of growth, reproduction, aging, and death. After the aging cells die, new cells will replace them to maintain the normal function of body tissues and organs. It can be seen that most cells in the human body can.
