Is nasopharyngeal cancer inherited from generation to generation?

Is nasopharyngeal cancer hereditary? Nasopharyngeal cancer often occurs in the nasopharynx between the nasal cavity and the oropharynx, most commonly at the top, followed by the side wall and the front wall, and least at the bottom. The anatomical location of nasopharyngeal cancer is hidden, and the symptoms and signs are variable, which are easily ignored by patients. Because the early symptoms of nasopharyngeal cancer are relatively common, it is also easy to be misdiagnosed by medical staff.

Genetic factors related to nasopharyngeal carcinoma: The incidence of nasopharyngeal carcinoma is obviously regional, and has obvious racial and familial clustering. Nasopharyngeal carcinoma is more common in the yellow race, and it is rare for Caucasians to suffer from this disease. If a family with a high incidence of nasopharyngeal carcinoma moves overseas, their descendants will still tend to have a high incidence rate.

Epidemiology has found that nasopharyngeal carcinoma has ethnic affinity and family clustering. The incidence rate of whites and blacks is very low; while the incidence rate in my country is high, and it is mainly distributed in southern cities, and many patients have a family history. Many people in high-incidence areas have settled in the United States. The incidence rate is still high in the first and second generations, and rarely occurs after the third and fourth generations. This shows that genetic factors alone will not cause disease, and other predisposing factors must be combined to form cancer; it also shows that genetics can be changed due to environmental changes. People with a family history should pay more attention to improving immune function and taking corresponding preventive measures to achieve the purpose of prevention.

Nasopharyngeal carcinoma refers to a malignant tumor that occurs in the nasopharyngeal mucosa. Guangdong, Guangxi, Fujian, Hunan and other places in China are high-incidence areas. Due to the influence of various physical, chemical and biological factors, the incidence of cancer is getting higher and higher. Nasopharyngeal carcinoma is indeed related to genetic factors, so many people who have already had nasopharyngeal carcinoma are worried about whether it will be inherited by their offspring. In fact, nasopharyngeal carcinoma is related to many factors. Infection with Epstein-Barr virus is obviously related to nasopharyngeal carcinoma, and there are also dietary factors.

The cause of nasopharyngeal cancer also includes avoiding the inhalation of harmful gases, such as asbestos, nickel, passive smoking, radiation, etc. Except for passive smoking, the others are all related to the pollution of the production environment, so the environment must be protected from pollution. We must also strengthen personal protection. We must pay attention to preventing other causes. Only genetic factors will not cause nasopharyngeal cancer.
