Nasopharyngeal carcinoma refers to the malignant tumors that occur in the nasopharynx. Clinically, most cases of nasopharyngeal carcinoma are due to symptoms caused by EB virus infection. Patients may experience dryness, itching, and pain in the nasal cavity, and in the morning, they may also have blood-tinged sputum and purulent secretion symptoms. In severe cases, patients may also experience symptoms such as tinnitus, ear pain, hearing loss, and ear congestion. If these symptoms occur, patients should first undergo a detailed examination with an electronic nasopharyngoscope and a CT scan of the nasopharynx to check for abnormalities. During the examination, the top of the nasopharynx may be found to be perforated, or cauliflower-like neoplasms or ulcers may be seen on the surface of the pharyngeal recesses. At this point, patients will need to undergo a local biopsy. Once confirmed as a malignant tumor, patients will need to undergo relevant radiation therapy and chemotherapy to prolong life.
