The U.S. government's Institute of Medicine reported that asbestos, which is accepted as a cause of a number of respiratory ailments including lung cancer, may also be a source for laryngeal cancer. The larynx produces the sound of your voice. Each year in the United States, more than 10,000 people learn they have larynx cancer. Men are four times more likely than women to get cancer of the larynx. Occupational related issues are certainly a factor with mechanics, construction, and other jobs that handle asbestos. A series of studies have found that certain cancers of the throat and lungs are similar, so the U.S. Senate asked the institute to investigate a potential link between asbestos and other upper-body cancers. Asbestos is also linked to mesothelioma which is a rare cancer that attacks the lining of the chest. Smokers and smokers that drink alcohol are even more at risk to develop cancer of the larynx. Symptoms of larynx cancer are hoarseness or other voice changes,lump in the neck, a sore throat or feeling that something is stuck in your throat, a cough that does not go away, breathing problems, bad breath, earaches, and weight loss.
