How is asbestosis diagnosed?

Diagnosis of asbestosis is largely dependent on a good and accurate clinical history taking. Occupational exposure to asbestosis is critical to the diagnosis. Histopathological diagnosis is usually not necessary for patient management but can be used to confirm the diagnosis. Screening of at-risk workers can reveal lung inflammation and lesions characteristic of

asbestosis. Patients' medical histories can identify occupations, hobbies, or other situations likely to involve exposure to asbestos fibers.

The person with asbestosis has abnormal lung function, and a doctor listening with a stethoscope placed over the lungs can hear abnormal sounds called crackles. In a person who has a history of exposure to asbestos, a doctor sometimes can diagnose asbestosis with a chest x-ray or a chest computed tomography (CT) that shows characteristic changes. X rays can show shadows or spots on the lungs or an indistinct or shaggy outline of the heart that suggests the presence of asbestosis. Blood tests are used to measure concentrations of oxygen and carbon dioxide. Pulmonary function tests can be used to assess a patient's ability to inhale and exhale, and a computed tomography scan (CT) of the lungs can show flat, raised patches associated with advanced asbestosis.

Pleural plaques that develop in many people with exposure to asbestos often contain calcium, which makes them easy to see on chest x-rays and CT. A lung biopsy is rarely needed to make the diagnosis. If a tumor of the pleura is found on x-ray, a doctor must perform a biopsy (remove a small piece of pleura and examine it under a microscope) to determine if it is cancerous.

More information on asbestosis

What is asbestosis? - Asbestosis is a chronic progressive disease characterised pathologically by interstitial fibrosis and asbestos bodies.
What is asbestos? - Asbestos is a natural mineral product known to be resistant to heat and corrosion. Asbestos causes cancer in the pleura, called mesothelioma.
What causes asbestosis? - Asbestosis is caused by long-term inhalation of asbestos fibers. There is an increased risk of lung cancer and mesothelioma associated with asbestosis.
What're the symptoms of asbestosis? - Symptoms of asbestosis include shortness of breath following exercise or other physical activity, dry cough and a generalized feeling of illness.
How is asbestosis diagnosed? - Diagnosis of asbestosis dependends on a good and accurate clinical history taking. Occupational exposure to asbestosis is critical to the diagnosis.
What's the treatment for asbestosis? - The goal of treatment for asbestosis is to help patients breathe more easily, prevent colds and respiratory infections, and control complications of asbestosis.
How to prevent asbestosis? - Anyone who works with asbestos should wear a protective mask or a hood with a clean-air supply and obey recommended procedures to control asbestos dust.
