People who handle asbestos material at their workplace:
- Workers who mine or process asbestos
- Construction workers
- Shipyard workers
- Vehicle mechanics
- Family members of people who work with asbestos and bring the fibers home on their hair or clothing
- People who work at sites where asbestos is found
- Shortness of breath—this is the first noticeable symptom and occurs with exercise or heavy effort
- Cough—the cough is persistent and nonproductive (which means no mucus is produced)
- Chest pain or tightness
- Feeling generally unwell
- Loss of appetite
- Finger clubbing, in some cases, caused by a build-up of fluid
- Weight loss
- Reliable history of exposure to asbestos
- Evidence of lung scarring and fibrosis which is based on a physical exam and/or additional tests
- Absence of other causes that may produce similar clinical pictures
- Chest X-ray—changes seen on the exam usually have a distinctive pattern
- CT scan —a type of x-ray that uses a computer to make pictures of structures inside the body. A high resolution CT is more sensitive that a plain x-ray in detecting abnormalities in individuals who were exposed to asbestos.
- Pulmonary function test—a test that measures how well the lungs take in and exhale air. The test can show if the lungs have reduced ability to function properly.
- Oximetry is a noninvasive means to assess oxygen status.
- Prevent further exposure to asbestos
- Stop smoking; people who have asbestosis and smoke cigarettes greatly increase their risk of developing lung cancer
- Getting immediate treatment for colds and other respiratory infections
- Staying updated with vaccinations, especially for flu (influenza) and pneumococcus
- Avoiding crowds, where infections might be spread
- Having regular chest x-rays to watch for signs of cancers associated with asbestos
- Having oxygen therapy and other respiratory therapies that can make breathing easier
- Improve the nutritional state
- Encourage breathing and physical exercises
- Home oxygen, if necessary
