Asbestos (C0003947)

Definition (MEDLINEPLUS)

Asbestos is the name of a group of minerals with long, thin fibers. It was once used widely as insulation. It also occurs in the environment. Asbestos fibers are so small you can't see them. Disturbing asbestos can cause fibers to float in the air. When this happens, they are easy to inhale. You breathe out most fibers, but some become lodged in the lungs. Over time, they can build up in the lungs, causing scarring and inflammation. This can eventually affect breathing and lead to disease, such as

  • Asbestosis, or scarring of the lungs that makes it hard to breathe
  • Mesothelioma, a rare cancer that affects the lining of the lungs or abdomen
  • Lung cancer

Lung diseases associated with asbestos usually develop over many years. Smoking cigarettes increases the risk.

Agency for Toxic Substances and Disease Registry

Definition (NCI) A group of minerals that take the form of tiny fibers. Asbestos has been used as insulation against heat and fire in buildings. Loose asbestos fibers breathed into the lungs can cause several serious diseases, including lung cancer and malignant mesothelioma (cancer found in the lining of the lungs, chest, or abdomen). Asbestos that is swallowed may cause cancer of the gastrointestinal tract.
Definition (MSH) Asbestos. Fibrous incombustible mineral composed of magnesium and calcium silicates with or without other elements. It is relatively inert chemically and used in thermal insulation and fireproofing. Inhalation of dust causes asbestosis and later lung and gastrointestinal neoplasms.
Definition (CSP) fibrous incombustible mineral composed of magnesium and calcium silicates with or without other elements; it is relatively inert chemically and has been used in thermal insulation and fireproofing; inhalation of dust causes asbestosis and later lung and gastrointestinal neoplasms.
Definition (NCI) One of a number of fibrous magnesium and calcium silicate minerals processed for thermal insulation and fireproofing. Asbestos is considered to be an environmental carcinogen; chronic inhalation of fine asbestos dust causes pulmonary asbestosis and may induce lung neoplasms. Chronic ingestion of asbestos may induce gastrointestinal neoplasms. (NCI04)
