There are many pathogenic factors of nasopharyngeal carcinoma, such as genetic factors. Many patients with nasopharyngeal carcinoma have a family history of cancer. Nasopharyngeal carcinoma is mainly found in yellow people and rare in white people. Nasopharyngeal carcinoma is also relatively concentrated in the region, mainly occurring in five southern provinces of China, Guangdong, Guangxi, Hunan, Fujian and Jiangxi. Southeast Asian countries are also high-risk areas. There is also the possibility of virus infection, and environmental factors can also cause nasopharyngeal carcinoma. Some trace elements, such as nickel, exceed the standard in the environment, which may also induce nasopharyngeal carcinoma.
The harm of nasopharyngeal carcinoma is that it will destroy the surroundings when it grows up, such as destroying the skull base, invading the skull, or destroying holes and great blood vessels, and will continue to extend forward to destroy the nasal cavity and orbit. Some patients with nasopharyngeal carcinoma will invade the jugular foramen near the nasopharynx, causing spinal nerve and cranial nerve paralysis and laryngeal paralysis, and patients with lymph node metastasis will have a lump in the neck.
The clinical manifestations are nosebleeds and nosebleeds, tinnitus and hearing loss. Clinically, many patients with nasopharyngeal carcinoma are found because of ear symptoms. Headache due to nasal congestion is a common symptom, which is mostly unilateral persistent pain in clinic, mostly occurring in the temporal parietal region. When nasopharyngeal carcinoma invades the nerves related to orbit or eyeball, it is already advanced. Nasopharyngeal carcinoma invades the eyes and often causes the following symptoms and signs: visual impairment, direct blindness, visual field defect, diplopia, exophthalmos and limited activity, neuropathic keratitis, optic atrophy and edema.
We should take more exercise to keep healthy. After all, health is the most important thing, and health is the capital of revolution.
