The causes of nasopharyngeal carcinoma are mainly due to air pollution, so we should pay more attention to the causes of nasopharyngeal carcinoma. So what are the causes of nasopharyngeal cancer? Chemical carcinogens in air There are many kinds of air pollutants that can induce the cause of nasopharyngeal carcinoma, among which asbestos, nickel, formaldehyde, smoke and tar, radiation, oil smoke and respirable dust are some of the more clear ones. All these air pollutants can induce the occurrence of nasopharyngeal carcinoma to some extent, and among them, the role of nickel in the occurrence of nasopharyngeal carcinoma is more thoroughly studied. Evidence of air pollution causing cancer Some investigations have shown that smoke from burning coal and wood in living rooms is related to the etiology of nasopharyngeal cancer in residents. Residents who cook indoors using a stove without a chimney are at greater risk of developing the disease than those with a chimney, and the risk increases when cooking in the living room. There is also evidence that the types and contents of elements in soil, drinking water, rocks, crops and human hair in areas with high incidence of nasopharyngeal cancer are consistent, and that the incidence of nasopharyngeal cancer is proportional to the nickel content of the strata. In addition, the incidence of lung cancer and nasopharyngeal cancer among workers in the nickel industry is 2.2-16 times and 39-196 times higher than that of the general population, which indicates that the inhalation of nickel dust can cause nasopharyngeal cancer, which is also the cause of nasopharyngeal cancer. Animal experiments have shown that after subcutaneous injection of dinitrosopiperazine in rats, nickel sulfate can promote the development of malignant tumors in the nasopharynx and its adjacent areas, which also indicates that nickel can promote the development of nasopharyngeal cancer caused by nitrosamines. The above-mentioned contents are the causes of nasopharyngeal cancer, and I hope you can understand them one by one. With these causes of nasopharyngeal carcinoma, we can live a better life and try to avoid the occurrence of this disease. Therefore, if you want to get rid of this disease, please keep these causes of nasopharyngeal cancer in mind. We wish all patients can recover soon.
