Pay attention to unilateral tinnitus and be careful of nasopharyngeal cancer

Guangdong is a high-incidence area for nasopharyngeal cancer, but so far no clear cause of the disease has been found, especially in cases of nasopharyngeal cancer in adolescents. Although the number of cases is small, the misdiagnosis rate is quite high. If early symptoms are not treated in time, the cure will be delayed. In addition, experts pointed out that the saying that "nasopharyngitis can cause nasopharyngeal cancer" circulated among some citizens is a serious misleading statement. There is absolutely no direct and inevitable connection between nasopharyngeal inflammation and nasopharyngeal cancer, and the treatment methods are completely different.

30% to 50% of nasopharyngeal cancer patients have a family history

The incidence of nasopharyngeal carcinoma is high in Guangdong, but so far, the exact cause has not been determined. After years of research, the causes of nasopharyngeal carcinoma are mainly in several aspects. The first is chemical carcinogenesis. For example, Guangdong people often eat pickled foods, which contain ammonium nitrite carcinogens. The second is environmental factors, generally referring to air pollution. Guangdong people often burn incense and firewood. The third is genetic factors. The gene location of nasopharyngeal carcinoma can be detected in the laboratory, and there is a saying of carcinogenic genes. In addition, many nasopharyngeal carcinomas have a family history. Currently, in a ward of Sun Yat-sen University Cancer Hospital, one-third to one-half of the 46 beds have a family history of tumors, and most of their immediate relatives suffer from nasopharyngeal carcinoma. Another basis is that Guangdong people who immigrate to Europe and the United States will also get sick. Many nasopharyngeal carcinoma patients in some European and American countries are Chinese, especially Guangdong Chinese.

It is worth noting that in daily life, 10% to 15% of normal people's EB virus serum will also test positive, but the higher the EB serum titer, the higher the incidence of nasopharyngeal cancer. When all three indicators are high, a biopsy should be performed.

In addition, the high-risk age group for nasopharyngeal cancer is 45 to 55 years old, and it gradually decreases after 60 years old. At the same time, it should be noted that the misdiagnosis rate of adolescent nasopharyngeal cancer is quite high. The main reason is that adolescent nasopharyngeal cancer is rare, the early symptoms are not obvious, and both doctors and patients often lack vigilance and are easily ignored. There are many cases of misdiagnosis or missed diagnosis in clinical practice, such as Xiaoye's case, which are very common. When faced with the symptoms of their children, many parents only know how to treat the symptoms, and never consider going to a specialist hospital for examination, which often delays treatment.

With the improvement of technology, nasopharyngeal cancer can be controlled and cured in most cases if it is discovered early. There was a 6-year-old nasopharyngeal cancer patient who was cured and has been admitted to university. There has been no recurrence since then. Radiotherapy is the first choice for nasopharyngeal cancer. It is not difficult to treat according to the course of treatment. The key is to detect it as early as possible. At present, the first national nasopharyngeal cancer early diagnosis and treatment demonstration base has been set up in Sihui, Guangdong. It mainly uses publicity and education to let more citizens understand and know about nasopharyngeal cancer.

To prevent nasopharyngeal cancer, do not trust the nasopharyngeal inflammation drugs advertised in drug advertisements. Second, insist on regular physical examinations. If conditions permit, regular blood EB virus tests can detect cancer at an early stage. Third, if you find that unexplained nasal congestion, nosebleeds, migraines, tinnitus and other symptoms are ineffective after using anti-inflammatory drugs for 3 to 5 days, you should consider a special examination. Fourth, patients originally from Guangdong should go to a specialist hospital for examination as soon as possible if a lump appears in the neck. Fifth, people with a family history of nasopharyngeal cancer should pay more attention to changes in nasopharyngeal diseases and check them in time if they find any discomfort.

There is a saying among some citizens: severe rhinitis and pharyngitis can lead to nasopharyngeal cancer. Nasopharyngeal inflammation is a disease caused by bacteria, while nasopharyngeal cancer is a tumor disease. There is no direct and necessary connection between the two. When nasopharyngeal inflammation occurs, symptoms such as nasal congestion, runny nose, and even bleeding will appear, while nasopharyngeal cancer will only have similar symptoms when complications occur. Nasopharyngeal cancer can develop to the middle and late stages within 3 to 6 months from the mutation of cancer cells. During this period, patients will have symptoms such as migraine, nasal congestion, nosebleeds, tinnitus, decreased vision, and severe cases are accompanied by lymph nodes. However, a considerable number of early patients have no obvious symptoms.

Experts pointed out that there are many kinds of misdiagnosis of nasopharyngeal carcinoma in clinical practice, especially in rural areas where medical and testing conditions are insufficient. The most common misdiagnosis is that a lump appears in the neck, which is misdiagnosed as lymph node inflammation. Some folk Chinese medicine practitioners treat it as "scrofula" (commonly known as big neck bubbles) and apply medicine. Some people also give anti-inflammatory injections for treatment. Later, the lymph nodes metastasize, and the patients mistakenly think that it is effective, but the cancer cells have not disappeared.
