Early and middle stage nasopharyngeal cancer usually needs about 35 times of radiotherapy, but the number of times of radiotherapy will change due to the different conditions of each person. Radiotherapy is the main method of treating nasopharyngeal cancer, which is a technique of intensity-modulated radiotherapy, in which the radiotherapy dose is concentrated in the tumor, killing the tumor cells while reducing the damage to other parts of the body. Usually, early and middle stage nasopharyngeal cancer needs about 35 times of radiotherapy. However, due to individual differences, if the tumor is under better control and the condition improves, or if the patient’s body can not tolerate radiotherapy, there may be only about 30 times of radiotherapy, therefore, the number of times of radiotherapy for early and middle stage nasopharyngeal cancer can not be generalized. After radiotherapy, patients should do a good job of local protection to avoid the skin treated by radiotherapy being exposed to sunlight, and at the same time, they should maintain oral hygiene, brush teeth and gargle diligently, as well as have a light diet and eat more fresh fruits and vegetables. If patients want to know the specific matters of radiotherapy for early and middle stage nasopharyngeal cancer, it is recommended to go to regular hospitals to consult doctors and under the guidance of doctors to carry out radiotherapy surgery.
