What is asbestosis?

Asbestosis is a process of lung tissue scarring caused by asbestos fibers. Because many other diseases also lead to lung scarring, other causes must be excluded first when a patient is found to have lung scarring (pulmonary fibrosis). Patients with particular x-ray findings or biopsy results must also have a remote history of asbestos exposure and a characteristically delayed development of the condition in considering asbestosis as a diagnosis. Smoking appears to increase the frequency and/or the rate of progression of asbestosis, possibly by preventing the efficient elimination of inhaled fibers from the airways.

What are symptoms and signs of asbestosis?

What are symptoms and signs of asbestosis?

The clinical symptoms usually include slowly progressing shortness of breath and cough, often 20 to 40 years after exposure to asbestos. Breathlessness advances throughout the disease, even without further asbestos inhalation. In the absence of cigarette smoking, sputum (mucus coughed up from the lungs) production and wheezing are uncommon. The exception is workers who have been exposed to very high concentrations of asbestos fibers. Those workers may also develop symptoms as soon as 10 years after exposure. Other indications of asbestosis include abnormal lung sounds on examination, changes in the ends of the fingers and toes ("clubbing"), a blue tinge to the fingers or lips ("cyanosis"), and failure of the right side of the heart ("cor pulmonale").

What is malignant mesothelioma?

What is malignant mesothelioma?

Asbestos is the only known risk factor for malignant mesothelioma (Asbestos Lung Cancer) , a cancer that affects the tissue lining the lung (pleura) or abdomen (peritoneum). Malignant mesothelioma is not associated with cigarette smoking but is strongly linked with the degree of asbestos exposure. However, 20% to 40% of patients with malignant mesothelioma have no prior asbestos exposure. In malignant mesothelioma, there is a very long duration between exposure and the onset of disease, usually greater than 30 years.
