Because of the danger, in many countries, including France, Japan, and Australia, expressed as a material banned asbestos. While in Indonesia, asbestos instead used for various purposes, including as housing materials such as ceiling, roof, etc..
Asbestos is a mineral that form fibers are easily separated. The size of an asbestos fibers are very small and delicate. Because that's easy to fly in the air. If inhaled, asbestos will soon enter into the respiratory cavity, resulting in various damages.
There are at least three diseases caused by asbestos dust. The first is mesothelioma, the malignant cancer of the lung veil, the veil of the stomach, or the veil of the heart. Both are lung cancer, asbestosis, and the latter disease. These diseases are often fatal and lead to death.
MesotheliomaAsbestos dust that has entered the lungs, will move up through the veil of the lungs. Here, the asbestos dust will damage the DNA of cells covering the lung (mesothelium), resulting in impaired cell growth control. Cells that have become abnormal will divide uncontrollably, and then expand and damage the surrounding tissue.
Lung CancerMechanism of occurrence of lung cancer caused by asbestos dust is similar to mesothelioma cancer. The difference, which is affected by airway wall (bronchiolus). Initially limited to damage the lungs, then at an advanced stage can metastasize to other organs.
AsbestosisAsbestos dust can cause irritation to the tissue and the sheath of the lungs. As a result of irritation, scar tissue will form a stiff. This network will slowly expand and thicken so that the lungs can no longer inflate and deflate like a normal lung.
This situation will cause various symptoms such as difficulty breathing, shortness of breath, coughing, and chest pain. In addition, pulmonary blood flow will also be blocked, forcing the heart to work harder. Eventually, the heart will enlarge. Scarring in the lungs called asbestosis caused by asbestos dust.
