What are the symptoms and causes of nasopharyngeal cancer

What are the symptoms of nasopharyngeal cancer? What is the cause?

Nasopharyngeal carcinoma is one of the most common malignant tumors in my country. It is more common in southern provinces such as Guangdong, Guangxi, Hunan, Fujian, and Jiangxi. The incidence rate in men is 2 to 3 times that in women. The age distribution of reported cases in my country ranges from 3 to 90 years old, but 30 to 50 years old is the high-incidence age group.

The main symptoms of nasopharyngeal carcinoma are as follows:

1. Nosebleed: Except for a few cases of bloody nasal discharge, there are basically no subjective symptoms. Especially in the morning, when the nose is bleeding, you should be more vigilant;

2. Headache: It is a common early symptom of nasopharyngeal carcinoma, accounting for 68.6%. It can be the first symptom or a symptom. In the early stage, the headache is not fixed and intermittent. In the late stage, it is a persistent migraine with a fixed location. The reason for this is that in early patients, it may be caused by neurovascular reflex or stimulation of the first branch of the trigeminal nerve. In late stage patients, it is often caused by tumors destroying the skull base and spreading inside the skull to affect the cranial nerves.

3. Refractory otitis media: manifested by one-sided ear canal discharge, tinnitus, hearing loss, and tympanic effusion. Such patients should have their nasopharyngeal area checked regularly for early detection;

4. Swollen lymph nodes in the neck: According to statistics, among the early symptoms of nasopharyngeal carcinoma, the incidence of swollen lymph nodes in the neck is relatively high. The specific location is a painless, hard, fixed lump below the mastoid muscle on the upper side of the neck, which grows relatively rapidly.
