The main causes of rhinitis cancer

Nasopharyngeal carcinoma refers to a malignant tumor that occurs in the nasopharyngeal mucosa. Its cause is related to many factors. It is necessary for us to understand nasopharyngeal carcinoma. Here we will talk about the main causes of rhinitis and cancer , hoping to help everyone.

1 Environment and diet

Environmental factors are also a cause of nasopharyngeal cancer. A survey in Guangdong found 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 content of nickel in the hair of nasopharyngeal cancer patients is also higher than that in areas with low incidence. Animal experiments show that nickel can promote nitrosamines to induce nasopharyngeal cancer. People who are easily exposed to formaldehyde in life are also prone to nasopharyngeal cancer. There are also reports that eating salted fish and pickled food is a high-risk factor for nasopharyngeal cancer in southern China, and it is also related to the age of eating salted fish, the period of consumption and the cooking method.

2 Genetic factors

There is a racial and familial clustering of nasopharyngeal cancer patients. For example, the descendants of southern Chinese living in other countries still have a high incidence of nasopharyngeal cancer, which suggests that nasopharyngeal cancer may be a hereditary disease. This is the main cause of rhinitis and cancer.

3Unilateral tinnitus

There is a Eustachian tube connecting the nasopharynx and the middle ear cavity, which can regulate the air pressure in the middle ear cavity and maintain the balance of pressure inside and outside the eardrum. Nasopharyngeal cancer often occurs near the opening of the nasopharyngeal tube. The tumor compresses the opening of the Eustachian tube, causing blockage. This is why tinnitus occurs in nasopharyngeal cancer. Therefore, once unexplained unilateral tinnitus occurs, especially in men over 30 years old, and those with ear closure, they should be highly alert to the possibility of nasopharyngeal cancer.

The above is an introduction to the main causes of rhinitis cancer. We must also do the corresponding preventive work in normal times. If you want to know more about nasopharyngeal cancer, please consult online experts.
