Nasopharyngeal cancer is one of the most prevalent malignant tumors in China, which brings great impact on people’s work and life. Timely treatment of nasopharyngeal cancer is the key, and careful people will find that the clinical treatment of nasopharyngeal cancer mostly adopts radiotherapy instead of surgery, why? 1, most patients’ nasopharyngeal carcinoma belongs to low decomposition squamous carcinoma, which is more malignant and easily invades around the nasopharynx and is prone to cervical lymph node transport, so it is difficult to be removed cleanly by surgery; 2, the nasopharynx is located in the center of the skull, which is more shaded and connected with important organs, cranial nerves and blood vessels, so surgical removal is extremely restricted, and surgical removal can easily damage the surrounding tissues, which is more dangerous and cannot Therefore, the effect of surgical resection alone is not very good; 3. 96% of nasopharyngeal cancer is low-decomposition squamous carcinoma, which has high sensitivity to radiation, and radiotherapy can easily put the primary lesion of nasopharyngeal cancer and cervical lymph node drainage area in the irradiation field, so the effect of radiotherapy is better. The five-year survival rate of nasopharyngeal cancer patients after radiotherapy can reach more than 52%; among them, the five-year survival rates of stage I and II patients are 96% and 77%, respectively. In addition, the summary of clinical investigation on nasopharyngeal cancer recurrence shows that secondary radiation therapy still has effective medical value for nasopharyngeal cancer. Most of the cancer patients who died were scared to death. Many people are very desperate after suffering from cancer and think that the treatment cannot be cured, so they give up the treatment. Therefore, cancer patients should not despair and must actively receive scientific treatment.
