Asbestos as cause of larynx cancer
Over the last several decades, a higher incidence of laryngeal cancer among workers exposed to asbestos has become apparent. Larynx 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 laryngeal 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 from the throat, or pharynx, can more directly be called pharyngeal cancer. Both throat cancers, pharyngeal and laryngeal (the latter affecting the voice box), are associated with high levels of asbestos exposure.
What are the symptoms of laryngeal cancer?
The symptoms of laryngeal 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 larynx cancer.
How is larynx cancer diagnosed?
According to the American Cancer Society, approximately 12,000 people are diagnosed with laryngeal cancer in the US each year. Based on your symptoms and associated risk factors (which include asbestos exposure) diagnosis will likely start with a basic physical exam, where your doctor feels your neck for abnormal swelling or lumps and looks at your throat. Either an indirect or direct laryngoscopy may follow. An indirect laryngoscopy is done using a long handled mirror and requires little more than an anesthetic spray. Direct laryngoscopy is done using a lighted tube to see further down the throat. Imaging, such as a CT scan, or biopsy (usually taken via the laryngoscope) are other diagnostic tools used to determine a larynx cancer diagnosis.
How do I know if my laryngeal cancer is asbestos-related?
If you know you have a history of asbestos exposure, there is a possibility that your laryngeal cancer is asbestos-related. Especially among non-smokers, a history of asbestos exposure is a common thread in larynx cancer diagnoses. Prior asbestos exposure may be revealed by the presence of pleural thickening or asbestosis in patients who have laryngeal cancer.
