Do you know what causes laryngeal cancer?

Nowadays, with the gradual deterioration of our living environment and the formation of bad habits among people, the occurrence of laryngeal cancer is not surprising. The disease can be divided into primary and secondary types according to different causes in clinical practice, and the harm it brings is also very great. So, how is laryngeal cancer caused? Many patients are confused, and the following is a detailed answer for everyone.

1. Smoking: Smoking is closely related to respiratory tumors. Most laryngeal cancer patients have a long history of heavy smoking. The incidence of laryngeal cancer is proportional to the daily smoking amount and the total smoking time. In addition, passive smoking cannot be ignored and may also cause cancer. When smoking, tobacco burns to produce tar, in which benzopyrene has a carcinogenic effect, which can cause mucosal edema, congestion, epithelial hyperplasia and squamous metaplasia, stop ciliary movement, and thus cause cancer.

2. Drinking: According to surveys, drinkers have a 1.5 to 4.4 times higher risk of laryngeal cancer than non-drinkers, especially supraglottic laryngeal cancer, which is closely related to drinking. Smoking and drinking have a synergistic effect in causing cancer.

3. Air pollution: Long-term inhalation of industrial dust, sulfur dioxide, chromium, arsenic, etc. may lead to respiratory tumors. The incidence of laryngeal cancer is high in cities with serious air pollution, and the incidence is higher in urban residents than in rural residents.

4. Occupational factors: long-term exposure to toxic chemicals such as mustard gas, asbestos, nickel, etc.

5. Viral infection: Human papillomavirus (HPV) can cause laryngeal papilloma, which is currently considered to be a precancerous lesion of laryngeal cancer.

6. Sex hormones: The larynx is a secondary sex organ and is considered a target organ for sex hormones. Male patients with laryngeal cancer are significantly more likely to have a higher level of testosterone than female patients. Clinical studies have found that laryngeal cancer patients have higher testosterone levels than normal people, lower estrogen levels, and testosterone levels significantly decrease after tumor removal.

7. Lack of trace elements: Certain trace elements are important components of some enzymes in the body. Lack may cause changes in the structure and function of the enzymes, affect cell division and growth, and cause gene mutations.

8. Radiation: Long-term exposure to radioactive nuclides such as radium, uranium, and radon can cause malignant tumors.

It can be seen that there are many factors that cause laryngeal cancer. Everyone should pay more attention to avoiding the above factors. For high-risk groups, they should pay attention to quitting smoking, drinking appropriately, and doing a good job of prevention. Early detection and early diagnosis and treatment are very important to reduce the harm of laryngeal cancer. On the one hand, it can improve the patient's survival rate after surgery. On the other hand, it is possible to preserve the pronunciation function of the larynx as much as possible and reduce postoperative complications.
