Nasopharyngeal carcinoma is a malignant tumor originating in the nasopharynx, and China is a region with a high incidence of nasopharyngeal carcinoma patients, with the highest incidence in Guangdong Province, which is known as “Guangdong cancer”. The ratio of male to female patients is about 3:1, and it can occur in all age groups, but most of them are between 40-60 years old. Genetic factors, pathological factors and environmental factors may be the causes of nasopharyngeal cancer. Because of the special anatomical location of nasopharynx, it is difficult to operate and more than 80% of nasopharyngeal carcinoma is low differentiated squamous carcinoma, which is more sensitive to radiation therapy, therefore, radiation therapy is the first treatment option for nasopharyngeal carcinoma. Therefore, the prevention and treatment of nasopharyngeal cancer lies in early detection, early diagnosis and early treatment. For those early signs of nasopharyngeal cancer, they must not be ignored because of carelessness. The symptoms are generally manifested as: nasal discharge with blood, nasal congestion, tinnitus hearing loss and headache. If these symptoms occur frequently for a period of time, then it is necessary to rush to the hospital for examination. It is worth noting that chronic rhinitis is more common in the population nowadays, and patients with long-term recurrent rhinitis have similar symptoms because they usually have similar symptoms, so some early symptoms of nasopharyngeal cancer can be easily ignored. Therefore, rhinitis patients should pay attention to the signs and go to hospital for nasal endoscopy in time to prevent misdiagnosis or missed diagnosis. Like digestive tract tumors, nasopharyngeal cancer is also one of the tumors where early lesions can be easily detected, yet it is the least likely to be detected. Because people prefer to go for professional endoscopy of the GI tract only after symptoms appear. In this regard, experts in the field have repeatedly emphasized that medical checkups for cancer prevention are different from ordinary physical examinations, and special examinations must be conducted in professional hospitals.
