Nasopharyngeal carcinoma is a malignant tumor occurring in the nasopharynx, which is a tumor of higher malignancy, with the majority of male patients, about twice as many as women.
The front wall of the pharynx is connected to the nasal cavity, oral cavity and larynx, so it can be divided into nasopharynx, oropharynx and laryngopharynx. The development of nasopharyngeal cancer is the result of many factors, including genetic factors, viral infection, environmental factors, and trace elements. If there are patients with nasopharyngeal cancer in the family, it will increase the prevalence of nasopharyngeal cancer; in addition, nasopharyngeal cancer is mostly seen in yellow people, but rare in white people. The development of nasopharyngeal cancer is closely related to the infection of EBV. Long-term exposure to nitrosamines and trace elements of nickel is also related to the development of nasopharyngeal cancer.
In the early stage, patients with nasopharyngeal carcinoma may suffer from snotty blood, tinnitus, hearing loss, nasal congestion, headache and swollen lymph nodes in the neck. Therefore, early detection, early diagnosis and treatment are extremely critical.
