Amphiboles, though less prevalent, are more pathogenic than chrysotiles, particularly with respect to induction of malignant pleural tumors (mesotheliomas). Indeed, some studies of mesotheliomas have shown the link is almost always to amphibole exposure.</spoiler>

* <spoiler text="What are asbestos bodies?">Asbestos bodies appear as golden-brown, fusiform or beaded rods with a translucent center. They are composed of an asbestos fiber coated with an iron-containing proteinaceous material. They arise when macrophages attempt to phagocytose asbestos fibers; the iron (ferritin) binds to the fiber within the phagocyte. Other inorganic particles may also be incorporated onto the asbestos fiber along with the ferritin.</spoiler>
