Asbestos as cause of throat cancer
Over the last several decades, a higher incidence of laryngeal cancer among workers exposed to asbestos has become apparent. Throat cancer is usually associated with higher levels of asbestos exposure. Like other asbestos-related diseases, evidence indicates a dose-response relationship, meaning the more asbestos you were exposed to, the greater the risk of developing throat cancer.
What is the difference between laryngeal cancer and throat cancer?
"Throat cancer" refers to cancers of both the pharynx (throat) and larynx (voice box). Cancer specifically arising specifically from the throat, or pharynx, can more directly be called pharyngeal cancer, however, the term "throat" is also used to refer to both the pharynx and larynx. We cover laryngeal cancer specifically elsewhere; this page covers cancer of the pharynx. Both pharyngeal and laryngeal cancers, are associated with high levels of asbestos exposure.
What are the symptoms of throat cancer?
The symptoms of throat cancer are not surprising considering the location of the affected tissue. Sore throat, cough, and difficulty swallowing are among the symptoms. A change in your voice, such as hoarseness, that does not resolve in 1 to 2 weeks, neck pain, a swelling or lump, unexplained weight loss, and high-pitched breathing sounds are also potential symptoms of throat cancer.
How is larynx throat diagnosed?
Approximately 24,000 Americans are diagnosed with throat cancer in the US each year; half of these cancers are located in the pharynx and half in the larynx. If you or your doctor is considering a throat cancer diagnosis, it is likely you are experiencing throat cancer symptoms and have some risk factors for throat cancer (including asbestos exposure). Your doctor is likely to start by getting a better look at your throat, through a basic physical exam, endoscopy (lighted scope), or laryngoscope (similar to the endoscope). More in-depth testing may follow, including the collection of tissue samples for laboratory testing (biopsy) and imaging test such as X-ray, CT scan, MRI, and PET scans.
How do I know if my throat cancer is asbestos-related?
If you know you have a history of asbestos exposure, there is a connection between throat cancer and asbestos exposure. Especially among non-smokers, a history of asbestos exposure is a common thread in throat cancer diagnoses. Prior asbestos exposure may be revealed by the presence of pleural thickening or asbestosis in some throat cancer patients.
