Mesothelioma Risk Depends on Asbestos Fiber Size

Scientists who study the connection between asbestos fibers and mesothelioma say they now understand what size particles pose the most danger. Asbestos is the primary cause of mesothelioma, but some manmade fibers can also be carcinogenic. Manmade nanotubes or nanoparticles are carbon molecules constructed for use in nanotechnology, electronics, optics and other fields of materials science. Some studies have suggested that their shape can allow them to cross membrane barriers inside the body and cause “inflammatory and fibrotic reactions.”  Such reactions are believed to be the same mechanism by which asbestos fibers may trigger malignant mesothelioma in the pleural membrane around the lungs. Although scientists have long known that the affects of fibers depends on their length, the “key threshold length” … Continue reading Mesothelioma Risk Depends on Asbestos Fiber Size »
