What are the late symptoms of nasopharyngeal carcinoma?

Nasopharyngeal carcinoma refers to a malignant tumor that occurs in the nasopharyngeal mucosa. Among the people with nasopharyngeal carcinoma, men are more likely to suffer from it than women. Because the early symptoms of nasopharyngeal carcinoma are not obvious, it is not easy to be discovered. By the time the symptoms of nasopharyngeal carcinoma become obvious, it is already in the late stage of nasopharyngeal carcinoma. So what are the symptoms of late stage nasopharyngeal carcinoma? Let's learn about it below.

1. Nasal congestion : The tumor invades the posterior nares and nasal cavity, which may cause obvious nasal congestion symptoms.

2. Bloody mucus or nasal obstruction : Since the tumor blood vessels in the nasopharyngeal cavity are relatively fragile, the surface of the tumor is often covered with numerous membranes, so there is a symptom of bloody mucus, which is one of the early symptoms of nasopharyngeal carcinoma. In severe cases, a large amount of nasal obstruction may occur. Bloody mucus often occurs in the morning after getting up, and bloody mucus is discharged from the mouth. The amount of blood is not large, and it is often neglected by patients or is mistaken for hemoptysis and sent to the respiratory department for diagnosis and treatment. This symptom is more common in patients with ulcers or cauliflower-shaped cancer lesions.

3. Eye symptoms : When nasopharyngeal carcinoma invades the eye socket or nerves related to the eyeball, visual impairment, exophthalmos, diplopia, and restricted eye movement may occur.

4. Ptosis and fixed eyeballs : related to oculomotor nerve damage. Visual impairment or loss is related to optic nerve damage or orbital cone invasion. Hoarseness and dysphagia are related to vagus nerve and glossopharyngeal nerve damage.

5. Diplopia : Due to the invasion of the abducens nerve by the tumor, double vision is often seen when looking outward. The invasion of the trochlear nerve often causes inward strabismus and diplopia, which is often damaged at the same time as the trigeminal nerve.

6. Tinnitus and hearing loss : caused by tumor infiltration and compression of the Eustachian tube, resulting in negative pressure in the tympanic cavity.

7. Headache : The most common symptom of nasopharyngeal cancer, often manifested as unilateral persistent pain, mostly located on the top of the face.

8. Tongue atrophy and tongue deviation : Direct invasion of nasopharyngeal carcinoma or lymph node metastasis to the posterior styloid process or hypoglossal nerve canal causes the hypoglossal nerve to be invaded, causing the tongue to deviate to the affected side, accompanied by tongue muscle atrophy on the affected side. If both hypoglossal nerves are damaged, it will cause difficulty in tongue extension. The incidence of tongue deviation is second only to facial anesthesia.

9. Facial numbness : refers to numbness of the facial skin, clinical examination shows decreased or absent pain and touch sensation. Tumor invasion of the cavernous sinus often causes damage to the first or second branch of the trigeminal nerve; tumor invasion of the oval foramen, the anterior area of ​​the styloid process, and the third branch of the trigeminal nerve often causes numbness or paresthesia of the skin in the front of the auricle, temporal region, cheek, lower lip, and chin.
