The incidence rate of nasopharyngeal cancer in men is about 2~3 times that of women, and the age of 40~50 is the high incidence age. Nasopharyngeal cancer accounts for 30.97% of systemic malignant tumors, 78.08% of head and neck tumors, and 92.99% of upper respiratory tract tumors. Can nasopharyngeal cancer be prevented? Because the cure rate can be as high as 90% if the tumor is detected early. So how can we prevent the occurrence of nasopharyngeal cancer? 1. Correct bad dietary habits: do not eat salted fish and pickled products. If you live in a region with a high incidence of disease or your immediate family members have a history of nasopharyngeal cancer, you should have a regular physical examination of the nasopharynx every year, and blood can be drawn to check EBV during the physical examination. 2.If abnormal symptoms appear, you should seek medical attention in time, rather than avoiding the disease. Early consultation can not only increase the cure rate but also reduce medical costs. 3.Earth, nose and throat specialists should be consulted instead of medical and surgical doctors, as non-specialists may also miss the diagnosis. 4.After being diagnosed with nasopharyngeal cancer, one should not be afraid and should not give up the treatment, for the patient, having a strong heart is more effective than any treatment. You should often do exercises such as neck turning, teeth knocking, cheek puffing, smiling and mouth opening. Patients with dry mouth can use the method of oral pear slices to alleviate discomfort; patients who develop radiopharyngitis, rinse with stomatitis compound before three meals and at bedtime. Strengthen nutrition, diet should be light, highly nutritious, easy to digest, eat less and more meals, and pay attention to the color and flavor of food and environmental neatness. Consume more fresh fruits and vegetables, such as carrot, white radish, tomato, lotus root, citrus, lemon, hawthorn, etc.
