Nasopharyngeal cancer radiotherapy interrupted for two months will have some effect on the treatment effect, which can be minimized by increasing the number of radiotherapy sessions to make up the dose at a later stage. Most of the pathological types of nasopharyngeal cancer are low-differentiated squamous carcinoma, which is sensitive to radiotherapy, thus radiotherapy is often taken as the first choice of treatment plan. If radiotherapy is interrupted for two months during the course of radiotherapy, it will have a certain impact on the treatment effect, but the dose loss caused by the interruption can be made up by appropriately increasing the number of radiotherapy sessions under the guidance of doctors. Nasopharyngeal cancer patients should try to diversify their diet, and they can eat more high protein, low fat and vitamin-rich foods, such as fish, milk, cabbage, oranges and so on. Eat less smoked and salted food and no spoiled food. When nasopharyngeal cancer appears, you need to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
