Can malignant laryngeal cancer be cured?

The following are several symptoms of this disease. The main symptoms of laryngeal cancer are hoarseness, dyspnea, cough, dysphagia, cervical lymph node metastasis, etc. High-risk groups should pay attention to quitting smoking, drinking moderately, 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, and on the other hand, it is possible to preserve the pronunciation function of the larynx as much as possible and reduce postoperative complications.

There is currently no definite cause of laryngeal cancer. It may be caused by the combined action of multiple factors, mainly the following aspects.

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 amount of smoking 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, the risk of laryngeal cancer in drinkers is 1.5 to 4.4 times higher than that in 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 tract 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 precursor 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 be diagnosed than female patients. Clinical studies have found that the testosterone level in laryngeal cancer patients is higher than that of normal people, and the estrogen level is lower; the testosterone level drops significantly after tumor removal.

7. Lack of trace elements

Certain trace elements are important components of some enzymes in the body. Their deficiency may lead to 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.
