Pleural plaques first appear around 20 years after a person is exposed to asbestos. Ahead of the 1970s, when asbestos legal guidelines came into effect, infinite workers in industries that include mining, construction and shipping were exposed to serious degrees of asbestos. Considering that it that it takes about 30-40 years for asbestos-related diseases such as asbestosis and mesothelioma to develop, the sufferers currently experiencing symptoms likely make up the last large wave of occupation-related asbestos disease cases.
What are plural plaques?
Plaques are little, localised areas of fibrosis caused by exposure to asbestos fibres, discovered throughout the pleura of each lung. The existence of pleural plaques is an indicator that a person has been disclosed to asbestos.
Like pleural thickening, pleural plaque is benign (non-cancerous) and cannot turn malignant. It is also, not necessarily a definite sign of an asbestos lung disease. Even so, many persons who develop pleural plaques also develop pleural effusion, asbestosis, malignant mesothelioma or even other asbestos-related diseases.
Pleural plaques could appear even with low-dose, intermittent exposure. This stands in contrast to asbestosis, or pulmonary fibrosis, which builds up only after a precise dose threshold has been crossed. However, pleural plaques happen to be present in patients with asbestosis and can be present in patients with mesothelioma.
While non-cancerous sorts of asbestos lung disease can be treated with medicament (for inflammation) and oxygen, malignant mesothelioma is lethal and nearly always worsens and leads to death.
Available Treatments...
When pleural plaques are clinically determined the illness does not call for any type of medical therapy. Since the plaques do not cause symptoms and their formation is non-life threatening their removal is pointless and no new treatments exist. Yet, patients that are diagnosed with pleural plaques are well advised to schedule regular check-ups. These regular physicals can help doctors monitor the growth and development of the plaques or scarring. As part of a typical check-up patients are requested to undergo pulmonary (breathing) tests to monitor lung function. Pulmonary tests, along with other routine tests, can be used to consider the patient's condition and rule out the development of other asbestos-related diseases.
