Why is nasopharyngeal carcinoma afraid of cold

summary

In October 2006, sputum with blood in the nose was found, and the diagnosis was early nasopharyngeal carcinoma. After treatment, it recurred in October 2009. Part of the skull was eaten by cancer cells, which often caused headache. After chemotherapy, they recuperated at home. Recently, there has been epistaxis, found a long tumor. I'm on chemotherapy. Now let's share why nasopharyngeal carcinoma is afraid of cold.

Why is nasopharyngeal carcinoma afraid of cold

First, family history is more common in NPC patients. In recent years, EB virus infection has been considered to be closely related to the occurrence of nasopharyngeal carcinoma. However, EB virus widely exists in people all over the world, and the occurrence of nasopharyngeal carcinoma has obvious regional characteristics, which indicates that EB virus infection is not the only cause of nasopharyngeal carcinoma.

Second, environmental factors may be related to a variety of chemical carcinogens, such as nitrosamines and trace element nickel. In addition, vitamin deficiency and sex hormone imbalance can change the sensitivity of mucosa to carcinogens. The rate of lymphocyte transformation and natural petal formation decreased, and the delayed skin anaphylaxis test weakened.

Third: the causes of nasopharyngeal carcinoma are: the environment and diet are easy to cause nasopharyngeal carcinoma. The content of trace element nickel in rice and water in high incidence area of nasopharyngeal carcinoma is higher than that in low incidence area. In the hair of NPC patients, nickel content is also high. Nickel may be a cancer promoting factor, leading to a high incidence of nasopharyngeal carcinoma. Dinitropropazine is associated with nasopharyngeal carcinoma.

matters needing attention

Radiotherapy is always the first choice for nasopharyngeal carcinoma. The 5-year survival rate is about 45%. Chemotherapy was used after radiotherapy to improve the curative effect and reduce the radiation reaction. If the tumor recurres after radiotherapy or is not sensitive or even ineffective to radiotherapy, surgery can be used. At present, the recovery rate of nasopharyngeal carcinoma is still very high.
