Top ten causes of nasopharyngeal cancer

The incidence rate of nasopharyngeal cancer is very high. Many people will encounter this disease, which will cause damage to their health. In severe cases, it can even be fatal. Therefore, we must correctly understand the knowledge of nasopharyngeal cancer and have a thorough understanding of the causes of this disease. What factors will cause the occurrence of nasopharyngeal cancer? Let's get to know it.

Factors that cause nasopharyngeal cancer:

1. Living environment: With the acceleration of my country's industrialization, environmental pollution is becoming more and more serious. Environmental pollution caused by industrialization is difficult to change in the short term. Although it is an irresistible factor, young people should be kind to themselves and their stomachs. Young people should pay attention to food hygiene, improve their self-care awareness, abandon bad living habits, and eat a regular, quantitative, and balanced diet.

2. Psychological pressure: Young people are in the development period of their careers, so they are prone to anxiety, tension and other negative emotions in their daily work. Nowadays, young people are under great pressure in life, and they are in a constant state of emergency mentally, which will feedback and induce intestinal diseases. Especially after suffering setbacks, anxiety will cause changes in the secretion of certain hormones and autonomic nervous function in the body, leading to digestive dysfunction and atrophic enteritis, which will induce nasopharyngeal cancer over time.

3. Lifestyle: Lifestyle is also an important cause of nasopharyngeal cancer. Many young people have irregular lifestyles, and drinking and smoking will affect their health. Many young people have no fixed place to live, no fixed jobs, like to stay up late to surf the Internet, and love to drink carbonated drinks, so they are infected with nasopharyngeal cancer at a young age. These unhealthy lifestyles may induce nasopharyngeal cancer.

4 Environment and diet

One of the causes of nasopharyngeal cancer is environmental factors, and improper diet can also lead to the occurrence of nasopharyngeal cancer. Environmental factors are also one of the causes of nasopharyngeal cancer. Experts have found through clinical research that the content of trace element nickel in rice and water in areas with high incidence of nasopharyngeal cancer is higher than that in areas with low incidence. The nickel content is also high in the hair of nasopharyngeal cancer patients. Nickel may be a cancer-promoting factor. Dinitrosopyrazine is related to the occurrence of nasopharyngeal cancer. Eating salted fish and pickled foods is a high-risk factor for nasopharyngeal cancer in southern China, and is related to the age, duration, frequency and cooking methods of eating salted fish. This is related to the high concentration of nitrosamine compounds in salted fish and pickled products;

5. Genetic Factors

According to clinical data, nasopharyngeal carcinoma can be inherited, so patients need to pay attention to whether there are nasopharyngeal carcinoma patients in their family. There is a racial and familial clustering of nasopharyngeal carcinoma patients, and nasopharyngeal carcinoma may be a hereditary disease. Recently, the correlation between certain genetic factors that determine HLA and nasopharyngeal carcinoma has been discovered. There are reports that peripheral blood lymphocyte chromosome aberrations in families with a high incidence of nasopharyngeal carcinoma are related to genetic susceptibility to nasopharyngeal carcinoma.

EB virus infection

The main cause of nasopharyngeal carcinoma is infection with EB virus, so we should pay more attention to preventing infection with this virus. Cells infected with EB virus can produce a variety of EB virus-specific antigens, including early antigens, shell antigens, membrane antigens and nuclear antigens. After being infected with EB virus, the human body will produce various corresponding antibodies. These antibodies can be used as serological diagnostic markers for nasopharyngeal carcinoma, but the positive rate of EA-IgA antibodies in normal people is relatively high, and it is not as specific as VCA-IgA in diagnosing nasopharyngeal carcinoma. Further studies have shown that the detection of EA-IgA antibodies in serum is more specific than VCA-IgA antibodies, but not as sensitive as VCA-IgA. People who are positive for VCA-IgA antibodies are at high risk of nasopharyngeal carcinoma.

7EBV virus infection.

Clinically, through long-term investigations, we know that EBV infection is closely related to the occurrence of nasopharyngeal carcinoma. Most keratinizing squamous cell carcinomas and most undifferentiated squamous cell carcinomas contain EBV. The body's immune function controls EBV infection through cellular immune function, and the probability of nasopharyngeal carcinoma is very high.

8 Chemical factors.

Through investigation, we know that when the hair is rich in nickel, the possibility of nasopharyngeal cancer is relatively high. Nickel has a promoting effect on nitrosamines, and formaldehyde is also a very important factor in inducing nasopharyngeal cancer.

9The occurrence of the disease is not only related to nitrosamines, polycyclic aromatic hydroxyls, and trace element nickel, but also closely related to the cooking methods and shelf life in daily diet.

10Genetic factors.

The occurrence of nasopharyngeal cancer has a clear family history, and the phenomenon of family clustering is also very serious. If there is a patient with nasopharyngeal cancer among family members, the probability of their offspring developing the disease is much higher than that of other people. The offspring of southern Chinese living in other countries also have a very high chance of developing nasopharyngeal cancer, which is hereditary.
