Asbestosis is a lung disease caused by inhalation of asbestos fibers. It is characterized by inflammation and scarring of the lungs, resulting in chest tightness and shortness of breath. Over time, asbestosis can lead to complications of heart disease, cancer and respiratory failure.

No Known Cure

Asbestosis can be treated but not cured. Treatment focuses on managing symptoms of the disease and may include:

  • Drug therapy

    oral steroids may help to reduce symptoms.

  • Oxygenation

    supplemental oxygen and pulmonary rehabilitation can help to reduce symptoms, maintain one's activity level, prevent some heart and lung complications, and improve quality of life.

  • Smoking cessation

    quitting smoking can help improve prognosis. Surgery: surgical intervention can help to prevent lung collapse in severe cases of the disease.

  • Surgery

    surgical intervention can help to prevent lung collapse in severe cases of the disease.

  • Lung transplantation

    when all other treatments have failed to provide symptom relief, lung transplantation may be an option.

Although asbestosis cannot be cured, it can be prevented by avoiding exposure to asbestos. Unfortunately, once an individual is exposed to asbestos, there is no known way to prevent the disease from developing. Maximum survival after symptom onset is about 4 years.1

Asbestos Exposure and Asbestosis

Asbestos is a mineral frequently used in the construction, shipbuilding, and automotive industries for its resistance to chemicals, heat, and fire, and its inability to conduct electricity. Given its significant health concerns, in 1989, the Environmental Protection Agency banned all new applications of asbestos. However, asbestos exposure is still one of the most common occupational hazards.

Everyone is exposed to low levels of asbestos in the air, soil, and water. However, it is prolonged, daily exposure to asbestos that most often leads to asbestosis. Professions with the highest risk of exposure to asbestos include:

  • Construction
  • Demolition
  • Manufacturing
  • Mining and milling
  • Automobile repair
  • Firefighting

Usually, it takes 10 to 40 years after exposure for symptoms of an asbestos-related disease to develop.

Complications of Asbestosis

 

Potential complications of asbestosis include:

 

  • Heart disease

    heart failure may develop secondary to scarring and compression of pulmonary vessels.

  • Cancer

    asbestosis is associated with the development of lung cancer and malignant pleural mesothelioma, one of the deadliest diseases attributed to asbestos exposure.

  • Respiratory failure

    as lung scarring worsens, lung expansion and oxygen diffusion are hindered, ultimately resulting in oxygen-deficient respiratory failure.
