1, the most common phenomenon is that patients cough up bloodshot sputum from the back of pharynx, which is called bloodshot sputum. This kind of blood phlegm is the secretion of bloodshot in the nasopharynx, and bloodshot, small blood clots or bloody secretions can also be seen in the nasal mucus, which are mostly coughed up or blown out through the nasal cavity in the morning or after getting up. If there is no bleeding part in the nasal passage and there is no chronic cough, it will cause certain symptoms when it appears. Because patients have no other symptoms, they are often mistaken for upper respiratory tract inflammation or lung disease.
2. Nasal congestion is also one of the early symptoms of nasopharyngeal carcinoma. It can swell at first, and a unilateral, painless and gradually increasing hard lump is often found in the deep part of the cervical mastoid muscle.
3. Patients with nasopharyngeal carcinoma may have tinnitus, headache or migraine in the early stage. Tinnitus is often unilateral, and its tone is like a high-pitched cicada or pulse beating sound. Headache is intermittent and may develop into persistence.
If the symptoms with unknown reasons mentioned above have no effect after treatment, you should go to the specialized outpatient department of the hospital and make a quick diagnosis after nasal endoscopy. Biopsy can also be done for suspicious masses. The method of examining exfoliated cells in the nasopharynx is very simple. You can find cancer cells by smearing them with cotton swabs or scraping nasopharyngeal secretions with steel rings.
Otolaryngology clinic of Wuhan Friendship Hospital has used nasopharyngeal fluorescein test, immunoassay test, isotope test and EB virus early antigen antibody test, which is helpful for early detection of nasopharyngeal carcinoma.
