What are the early symptoms of nasopharyngeal carcinoma

What are the early symptoms of nasopharyngeal cancer?

1. 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.

2. Headaches may occur in the early stage, and they are often biased to one side and intermittent. Symptoms such as nasal congestion, ear closure, tinnitus, numbness of the cervix, diplopia, and sagging of the upper cervix may also occur. 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 inhaling, which is also one of the early symptoms. During the examination, the neck lumps are mostly hard, with small nodules on the surface, and are difficult to move because of adhesions with the surrounding areas. Sometimes they fuse with each other to form a huge mass on the entire side of the neck.

3. Late-stage cancer is prone to invade the brain and metastasize to distant sites such as bones, liver, and lungs. To be cautious, patients should go to the hospital for a checkup: Generally, a nasopharyngeal endoscopy is performed first to see if there are any abnormalities on the surface of the nasopharynx, such as ruptures, ulcers, or masses. If there are masses, further examinations are required, such as blood tests, CT, and MRI. If subsequent examinations support the diagnosis of cancer, a biopsy is performed to confirm the diagnosis.
