What are the causes of nasopharyngeal cancer

The causes of nasopharyngeal carcinoma are related to multiple factors such as genetics, environment, and Epstein-Barr virus infection. Early detection and treatment are the key. The causes of nasopharyngeal carcinoma are complex, mainly including genetic susceptibility, Epstein-Barr virus infection, environmental factors, and bad living habits.

1. Genetic factors

The higher incidence of NPC in certain regions and families suggests that genetic susceptibility plays an important role in the onset of the disease. People with a family history of NPC have a significantly increased risk of the disease. Gene mutations may cause cells to grow out of control and develop into cancer.

2. Epstein-Barr virus infection

Epstein-Barr virus is one of the important pathogenic factors of nasopharyngeal carcinoma. After Epstein-Barr virus infection, viral DNA may be integrated into the host cell genome, leading to abnormal cell proliferation. People who have been infected with Epstein-Barr virus for a long time, especially those who are positive for Epstein-Barr virus antibodies, have a higher risk of nasopharyngeal carcinoma.

3. Environmental factors

Carcinogens in the environment may also induce nasopharyngeal cancer. Long-term exposure to chemicals such as nitrosamines and formaldehyde, or inhalation of large amounts of industrial dust and smoke, will increase the risk of disease. Nitrite in pickled foods is also a potential carcinogen.

4. Bad living habits

Bad living habits such as smoking and alcoholism are closely related to the occurrence of nasopharyngeal cancer. Harmful substances in tobacco can directly irritate the nasopharyngeal mucosa and increase the risk of cancer. Long-term drinking may reduce the body's immunity and promote the development of cancer.

5. Pathological factors

Chronic inflammation and nasopharyngeal diseases may also induce nasopharyngeal carcinoma. Long-term chronic inflammation can cause repeated cell damage and repair, increasing the risk of gene mutation. Nasopharyngeal polyps, adenoids hypertrophy and other diseases may also become precancerous lesions.

Treatments include radiotherapy, chemotherapy, and surgery. Radiotherapy is the preferred treatment for nasopharyngeal carcinoma, and commonly used techniques include intensity-modulated radiotherapy and proton therapy. Chemotherapy drugs such as cisplatin and paclitaxel can assist radiotherapy to improve efficacy. For patients with locally advanced disease, surgical resection may be used as a supplementary treatment. In terms of diet, it is recommended to consume more foods rich in vitamins C and E, such as citrus fruits, nuts, etc., to enhance immunity. In terms of exercise, moderate aerobic exercise such as walking and yoga can help improve physical fitness.

Prevention and early detection of nasopharyngeal carcinoma are crucial. Regular physical examinations, avoiding exposure to carcinogens, and improving lifestyle habits are effective measures to reduce the risk of disease. For high-risk groups, such as those with a positive family history or Epstein-Barr virus infection, screening and monitoring should be strengthened. Early diagnosis and treatment can significantly increase the cure rate and improve the quality of life of patients.
