石棉是引起支气管癌和间皮瘤的致癌物质。其它器官癌与石棉有关的包括胃肠道癌、卵巢癌和网状内皮系统癌。但喉癌与接触石棉的关系尚无人报告。人体呼吸道吸入石棉粉尘主要取决于其纤维大小。1973年Evans等给鼠做实验发现有0.5~1 .7%带有放射标记的石棉沉积在喉内,虽然大部分经由粘液纤毛迅速转送到胃肠道并从自然途径排除,但在喂部的石棉具有穿透和
Asbestos is a carcinogen that causes bronchial and mesothelioma. Other organ cancers are asbestos-related and include gastrointestinal, ovarian, and reticuloendothelial cancers. However, there is no report on the relationship between laryngeal cancer and asbestos exposure. Inhalation of asbestos dust in the human respiratory tract mainly depends on its fiber size. Evans et al. (1973) found that 0.5 to 1.7% of radiolabeled asbestos was deposited in the larynx. Although most of the aspirates were rapidly transported to the gastrointestinal tract via mucociliary cilia and were excluded from the natural pathway, Asbestos has penetrating and
