Asbestos is a mineral that form fibers separate easily. The size of the asbestos fibers are very small and delicate. This will make asbestos  fly easily on the air. When inhaled, asbestos will soon enter into the respiratory cavity, and causing various damage.

At least there are 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. The second is lung cancer, and the last Asbestosis disease. These diseases are often fatal and lead to death.

Mesothelioma

Asbestos dust that has entered the lungs, will move up to the veil of the lungs. Here, the asbestos dust would damage the DNA of cells covering the lung (mesothelium), consequently disrupted cell growth control. Cells that have become abnormal will divide uncontrollably, and then expand and damage the surrounding tissue.

Lung Cancer

Mechanism incidence of lung cancer due to asbestos dust is similar to mesothelioma cancer. The difference, which is affected by airway wall (bronchiolus). Initially limited to damage the lungs, and then at an advanced stage can metastasize to other organs.

Asbestosis

Asbestos dust can also cause irritation to the tissue and lung sheath. As a result of irritation, scar tissue will form a stiff. This network will gradually expand and thicken so that the lungs can no longer expand and deflate like a normal lung. This situation will lead to a variety of symptoms such as difficulty breathing, shortness of breath, cough, and chest pain. In addition, blood flow lungs will also be blocked, forcing the heart to work harder. Over time, the heart will be enlarged. The emergence of scar tissue in the lungs due to asbestos dust called Asbestosis.
