What is nasopharyngeal cancer

What is nasopharyngeal cancer?

The incidence of nasopharyngeal carcinoma in men is much higher than that in women. Genetic factors are relatively common in nasopharyngeal carcinoma patients. The occurrence of nasopharyngeal carcinoma is obviously regional, and viral infection is also one of the factors causing the disease. A variety of chemical carcinogens can change the sensitivity of the mucosa to carcinogens.

Most nasopharyngeal carcinomas originate from the reserve cells of the columnar epithelium of the nasopharyngeal mucosa. The reserve cells are primitive multipotent cells that can differentiate into columnar epithelium or squamous epithelium. Symptoms include nasal congestion, ear closure, tinnitus, numbness of the temples, diplopia, and sagging of the upper cervix. It often occurs in the pharyngeal recess and the anterior wall of the nasopharynx. The primary cancer breaks through the surface mucosa and bloody mucus appears. After getting up in the morning, the nasal secretions often contain blood or blood clots when inhaled. This is also one of the early symptoms. During examination, the neck lumps are mostly hard, with small nodules on the surface, and are difficult to move because of adhesions with the surrounding area. Sometimes they fuse with each other to form a huge mass on the entire side of the neck.

Patients should actively accept treatment and maintain a good attitude. When the climate changes, they need to keep warm, prevent colds, maintain nose and throat hygiene, and avoid viral infections. Try to avoid places with smoke, and patients are advised to quit smoking and drinking.
