Definition
Asbestos is a commercial term for a group of crystalline silicates that are composed of long thin fibers. Formerly, the noncombustible mineral was incorporated into a great variety of industrial and building materials. However, asbestos can be easily broken into tiny microscopic fibers and inhaled. In the lungs, the indestructible fibers may, over time, increase in size due to acquisition of ferritin/hemosiderin from proximal dying macrophages. After many years, the inhaled fibers can be carcinogenic. Thus commercial use of asbestos has been banned.
Characteristics
Carcinogenic Action of Iron
During the past 80 years, authors of scores of clinical and laboratory studies have reported that one of the many dangers of excessive/misplaced iron is its ability to initiate and to promote neoplastic cell growth. Initiation occurs via iron-catalyzed formation of reactive oxygen radicals (reactive oxygen species; oxidative stress) that, when generated in close proximity to DNA, can...
