Correlation between occupational asbestos exposure and esophageal cancer has been demonstrated by the existence of fibers stuck in the throat upon biopsies and other medical diagnosis tests. As for laryngeal cancer, The International Agency for Research on Cancer agreed that asbestos exposure can lead to it, as asbestos fibers can get stuck in the vocal cords causing it.
As in the case of the other diseases caused by asbestos exposure, esophageal and laryngeal cancer may develop following the inhalation or ingestion of toxic airborne asbestos fibers. Because asbestos fibers have a needle-like shape, they can easily embed themselves in the lining of the esophagus or larynx, where they will gradually cause inflammation and tissue scarring. Subsequently, a malignant tumor may grow. Moreover, if asbestos fibers made their way into the lungs, some of them may become stuck in the esophagus or larynx when coughing. It is not uncommon for victims of exposure to suffer from two related diseases at the same time when it comes to asbestos, such as lung cancer and esophageal cancer.
