Homing in on rising toll of asbestos
The Office of Asbestos Safety, announced by the Federal Government last week, will develop a plan to remove asbestos from government and commercial buildings by 2030 and label asbestos in homes to alert tradesmen, tenants and buyers.
MESOTHELIOMA EXPLAINED: This incurable cancer occurs in the pleural tissue layers that coat the inside of the chest wall and the outside of the lung and is almost always caused by asbestos exposure, according to Edward Fysh, Sir Charles Gairdner Hospital respiratory physician and Lung Institute of WA researcher.
Once inhaled, the long, pointy, sharp asbestos crystals spear through the airway walls and deposit in the pleural space, where they cause ongoing, low-grade inflammation. The immune system often fails to clear these fibres.
These fibres over time, often 20-40 years after inhalation, lead to the development of mesothelioma. While not all people exposed to asbestos will develop mesothelioma, a small exposure can be enough to trigger the cancer.
