Is the saliva of nasopharyngeal cancer contagious?

Nasopharyngeal carcinoma is a malignant tumor disease. This phenomenon of nasopharyngeal carcinoma is called genetic susceptibility. So, is the saliva of nasopharyngeal carcinoma patients contagious? In fact, kissing virus transmission leads to nasopharyngeal carcinoma. Therefore, it can be said that the saliva of nasopharyngeal carcinoma patients is contagious to a certain extent, and everyone must take precautions.

The pathogenesis of this disease can be understood in this way. The genetic material (DNA in the eyes of professionals) of these high-cancer family members is less stable and is more likely to mutate and form cancer when exposed to certain carcinogens. It can also be understood from another perspective. These high-cancer family members have a poor ability to resist carcinogens and have a lower threshold for cancer. Normal people will develop cancer only after long-term exposure to a large amount of carcinogens, while these high-cancer family members will develop cancer after only being exposed to a small amount of carcinogens. It's like natural water boils when heated to 100°C, while some special water only boils when heated to 60°C.

For people with high cancer families, how to do a good job of prevention? Although a large number of researchers have been committed to finding susceptibility genes for nasopharyngeal carcinoma, and want to change the characteristics of susceptibility genes through gene therapy to achieve the purpose of preventing nasopharyngeal carcinoma. But so far, there has been no major breakthrough in this research, and there is still a long way to go for genetic prevention. Although the susceptibility gene cannot be repaired at present, prevention work can be done from the following aspects: First, you should actively participate in physical exercise, combine work and rest, and enhance the body's resistance. Secondly, develop good living habits, do not smoke, do not drink alcohol, and eat healthily. Thirdly, minimize contact with carcinogens and avoid engaging in occupations that have contact with carcinogens. Finally, go to the hospital for regular physical examinations and strive for early detection and early treatment, because the treatment effect of early nasopharyngeal carcinoma is very good.
