About Asbestos

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. If you disturb asbestos, the fibers can float in the air. This makes them easy to inhale, and some may become lodged in the lungs.

If you breathe in high levels of asbestos over a long period of time, the fibers can build up in the lungs. This causes scarring and inflammation, and can affect breathing. Eventually it can lead to diseases 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. People who become ill from asbestos are usually exposed on the job over long periods of time. Smoking cigarettes increases the risk.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Asbestos

17 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
