The occurrence of laryngeal cancer is closely related to the current serious air pollution, but it may also be caused by excessive wear and tear in special occupations. For example, teachers, training lecturers and other occupations that need to talk frequently often have problems such as sore throat and damaged vocal cords. Severe or hoarse all the year round, if you don't pay attention, you are likely to suffer from laryngeal cancer.
I still remember that in the postgraduate training class, all the teachers who trained me were hoarse to varying degrees, and even gave lectures constantly, such as Qingyan Liyan tablets or American ginseng tablets.
Most people don't care about hoarseness, because there are many reasons for hoarseness, such as vocal polyps or vocal nodules, which will not attract enough attention and ignore the possibility of laryngeal cancer. Although the malignant degree and incidence of laryngeal cancer are lower than other cancers, it is the most common laryngeal malignant tumor, and the incidence rate is mostly in people over 50 years old, and males are significantly higher than females.
These problems should still be vigilant! Cancer cells grow on vocal cords, which are easy to identify, with low malignancy and good prognosis. Because it can cause hoarseness, it is easy to find it in the early stage. But if it grows on the glottis, it is more difficult to find and it will be mistaken for chronic pharyngitis. Therefore, if there is no inducement, symptoms such as foreign body sensation in the pharynx and hoarseness appear, we should be vigilant. Especially when there are voice, breathing and swallowing dysfunction, you should go to the hospital for examination in time. After laryngoscope, imaging examination and pathological diagnosis, the diagnosis can generally be made.
The teacher is in class.
Treatment of laryngeal cancer, early detection and early treatment, the effect is good, the five-year survival rate is generally above 85%. Doctors with five drugs and five drugs suggest that those who have hoarseness for more than 2 weeks and have not improved after medical treatment and proper rest, as well as men over 50 years old, should go to the hospital for throat examination in time.
Other people who are prone to laryngeal cancer are injured because of various reasons. In addition to overeating, people with a history of chronic pharyngitis and long-term smoking also have a higher risk of laryngeal cancer.
In addition, drinking is also one of the incentives. The damage of alcohol to laryngeal mucosa epithelium increases the possibility of laryngeal cancer. At the same time, people who smoke and drink will have a superimposed carcinogenic effect.
The basis of occupational diseases is the current Law on the Prevention and Control of Occupational Diseases. Occupational disease refers to diseases caused by contact with dust, radioactive substances and other toxic and harmful substances. Laryngeal cancer cannot be identified as an occupational disease, but the factors that cause laryngeal cancer do have occupational reasons.
As long as occupational diseases can cure cancer, asbestos can cause lung cancer and mesothelioma, benzidine can cause bladder cancer, benzene can cause leukemia, chloromethyl ether and dichloromethyl ether can cause lung cancer, arsenic and its compounds can cause lung cancer and skin cancer, vinyl chloride can cause hepatic angiosarcoma, coke oven waste gas can cause lung cancer, hexavalent chromium compounds can cause lung cancer, pilose zeolite can cause lung cancer and pleural mesothelioma, and coal tar, coal tar pitch and petroleum pitch can cause skin cancer. -Naphthylamine can cause bladder cancer.
