What does radiotherapy look like? 1.How does radiotherapy work? Radiation therapy is a special device that uses high doses of radiation to reach tumor cells and stop the cells from dividing and growing by breaking the DNA strands within the tumor cells. 2.By what means does radiotherapy work? Broadly speaking, there are three ways of radiotherapy: external irradiation, internal irradiation, and total body irradiation, and in some cases, more than one type of irradiation is required. 3.What will happen during radiotherapy? During treatment you will lie on a bed next to a linear gas pedal that has an arm that can rotate around the bed and irradiate you at different angles as needed. You talk to the technician through an intercom during the process. 4.What is the cost of radiation therapy? Depending on the complexity and technical content of the radiotherapy technique, the specific cost is mainly determined by the type of radiotherapy and the cost of intensity-modulated radiotherapy is higher than that of conventional radiotherapy. 5.Do I need to take off my clothes for radiotherapy? Depending on the treatment area, you may need to undress during the treatment, so it is recommended that you wear clothes that are easy to put on and take off. 6.Are I radioactive after radiotherapy? External radiation affects the cells inside your body for a short time because there is no radiation source inside your body, so you do not need to worry about being radioactive during or after radiotherapy.
