Can laryngeal cancer be cured

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.

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 burning can produce tar, in which benzopyrene is carcinogenic, which can cause mucosal edema, congestion, epithelial hyperplasia and squamous metaplasia, and stop ciliary movement. According to surveys, drinkers are 1.5 to 4.4 times more likely to develop laryngeal cancer than non-drinkers, especially supraglottic laryngeal cancer, which 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 have a higher incidence than rural residents. The larynx is a secondary sexual organ and is considered to be a target organ for sex hormones. There are significantly more male laryngeal cancer patients than female 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 resection. Most of them originate from the root of the lingual surface of the epiglottis. There are no symptoms in the early stage. Even when the tumor develops to a considerable extent, there are only mild or non-specific sensations, such as itchy throat, foreign body sensation, and swallowing discomfort. These sensations often cause alarm only when the tumor metastasizes to the lymph nodes. This type of tumor is poorly differentiated and develops rapidly. When deep infiltration occurs, there may be throat pain that radiates to the ears. If the tumor invades the spoon-shaped cartilage, the glottis, or the recurrent laryngeal nerve, it may cause hoarseness. In the late stage, patients will experience difficulty breathing and swallowing, coughing, blood in sputum, and coughing up blood. Patients over middle age who have persistent discomfort in the throat should pay attention to it, check it in time, detect the tumor early, and treat it.
