Is laryngeal cancer contagious?

Laryngeal cancer is a malignant tumor disease, not an infectious disease, so it is not contagious. There is no problem with normal contact and eating with laryngeal cancer patients. There are many factors that induce laryngeal cancer. If it is a direct relative, you must consider whether there is a genetic problem. Generally speaking, people with a family history of genetic diseases have a higher chance of getting the disease than normal people. Therefore, if it is a direct relative, you must pay attention to regular physical examinations. It is very important to detect and treat it in time.

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 no definite cause of laryngeal cancer. It may be caused by the combined effect of multiple factors, mainly the following aspects. 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 burning can 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. According to surveys, drinkers are 1.5 to 4.4 times more likely to develop laryngeal cancer than non-drinkers, especially supraglottic laryngeal cancer is closely related to drinking. Smoking and drinking have a synergistic effect in carcinogenesis. 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 urban residents are higher than rural residents. Occupational factors, long-term exposure to toxic chemicals such as mustard gas, asbestos, nickel, etc. .Viral infection: Human papillomavirus (HpV) can cause laryngeal papilloma, which is currently considered a precancerous lesion of laryngeal cancer. Sex hormones: The larynx is a secondary sex organ and is considered a target organ for sex hormones. Male laryngeal cancer patients are significantly more common than female laryngeal cancer patients. Clinical studies have found that laryngeal cancer patients have higher testosterone levels than normal people and lower estrogen levels; testosterone levels drop significantly after tumor removal. Trace element deficiency: Certain trace elements are important components of some enzymes in the body. Deficiency may cause changes in the structure and function of enzymes, affect cell division and growth, and cause gene mutations.
