Causes of nasopharyngeal cancer

At present, the harm of nasopharyngeal cancer is extremely serious. Many people will be harmed by nasopharyngeal cancer, which will interfere with their lives and cause damage to their noses. Therefore, we must correctly understand the knowledge of nasopharyngeal cancer, pay attention to the causes of the disease, and understand what are the causes of this disease.

Environmental factors are a cause of nasopharyngeal cancer. Eating too much salted fish, cured meats, and pickled foods containing nitrosamine compounds can induce nasopharyngeal cancer. Drinking water contains high levels of nickel and lead, while zinc, copper, and cadmium are relatively low. Rice contains high levels of nickel, while molybdenum, chromium, lead, and cadmium are low. Changes in these trace elements may also be related to the occurrence of nasopharyngeal cancer. In Guangdong, surveys found that the content of trace element nickel in rice and water in areas with a high incidence of nasopharyngeal cancer was higher than that in areas with a low incidence. The nickel content is also high in the hair of nasopharyngeal cancer patients. Animal experiments have shown that nickel can promote nitrosamine-induced nasopharyngeal cancer. Epstein-Barr virus, lymphoblastoid cell lines carrying Epstein-Barr virus were isolated from nasopharyngeal cancer tissues, and Epstein-Barr virus particles were found. There are high titers of antibodies to Epstein-Barr virus in nasopharyngeal cancer patients. The titers are high in those with severe conditions. As the condition recovers, the antibody titers decrease, indicating that Epstein-Barr virus is closely related to nasopharyngeal cancer.

Pickled food. Studies have found that frequent intake of pickled food such as salted fish, pickled meat, and pickled vegetables is one of the causes of nasopharyngeal cancer. These foods contain high levels of nitrite, and high concentrations of nitrosamines and dinitrosopiperazines are precipitated during cooking. These compounds can induce cancer. Genetic factors. Nasopharyngeal cancer patients have racial and familial clustering. For example, the descendants of southern Chinese living abroad still have a high incidence of nasopharyngeal cancer. Studies have also found that certain genetic factors that determine human leukocyte antigens (HLA) are closely related to the occurrence and development of nasopharyngeal cancer.

The first reason is that pickled products contain carcinogenic nitrosamines. In the process of processing pickled foods, a lot of salt is added, and the salt contains impurities such as nitrites and nitrates, which may produce some harmful substances such as nitrosamines. During the pickling process, if the amount of salt added is less than about 15%, the nitrates in the vegetables may be reduced to nitrites by microorganisms. If it is pickled for 1 hour, the nitrite content will increase. If it is after two weeks, it can reach a peak and may last for about 2 to 3 weeks.

Why do pickled foods become the cause of nasopharyngeal cancer? Pickled foods can produce a carcinogen called nitrosamines. If eaten frequently, it will be harmful to our body and may induce cancer. For example, natural vegetables such as radish, snow vegetable, and cabbage contain a certain amount of non-toxic nitrates. If the salt used in pickling vegetables is less than 10%, and the temperature is relatively high, and the pickling time is less than 8 days, it will cause a large number of bacteria to multiply, and nitrates are more easily reduced to toxic nitrites.

If you often eat pickled products, it is easy to cause vitamin C deficiency and stones in the human body, because in the process of pickling vegetables, vitamin C will be destroyed in large quantities, and its components will be almost wiped out. If you eat a lot of pickled vegetables, it may cause vitamin C deficiency in the human body. Therefore, you should eat some pickled vegetables appropriately, which can increase appetite and thus regulate appetite. However, if you become addicted to pickled vegetables and eat them for a long time, it will easily cause various diseases.

The above knowledge is the factors that induce the occurrence of nasopharyngeal cancer. This disease is quite complicated and will cause a lot of harm to the patient, and it will also make the patient particularly painful. Therefore, we need to be more vigilant about the occurrence of this disease, clearly understand the causes of nasopharyngeal cancer, and pay attention to the relevant prevention of nasopharyngeal cancer.
