There is no cure, although oxygen supplied via mask at home helps in advanced cases. Now that high exposure to asbestos in the workplace no longer takes place, it's becoming increasingly rare. Asbestosis requires a great deal of exposure to asbestos to develop and is usually seen in former asbestos miners, asbestos manufacturing workers and insulation workers. It usually takes at least ten years to develop after exposure to asbestos, but once it does, the symptoms get progressively worse, though the rate at which the disease progresses varies enormously. The affected person feels a tightness in the chest, has a dry cough, and in the later stages, a bluish tinge to the skin caused by lack of oxygen. The lungs become stiff, and breathing becomes more difficult over time. AsbestosisĪsbestosis is scarring of the lungs due to asbestos exposure. The procedure may need to be repeated if the fluid gathers again. A doctor passes a needle through the chest wall into the pleural cavity under local anaesthetic and drains the fluid. If there is pleural effusion, it can be drained to relieve the breathlessness. This is known as pleural effusion.īenign pleural disease is not dangerous or fatal, although it may restrict breathing. The inflamed pleura can also secrete fluid into the pleural cavity the space between the two pleural layers. This thickening can be widespread (known as diffuse thickening) or it can occur in patches, known as plaques. The pleura is the lining of the lung that helps the lung glide over the chest wall as it expands and contracts during breathing.Īsbestos fibres can irritate and thicken the pleura. One of the effects of inhaled asbestos fibres is to irritate and inflame the pleura of the lung. People involved in uncontrolled removal of asbestos are also at risk.Ĭurrently, most people exposed to asbestos are maintenance and demolition workers employed to work in old buildings undergoing renovation or demolition. ![]() Those most at risk of asbestos-related disease are people exposed to asbestos while working in the mining, manufacturing, building and construction industries. People are getting asbestos-related lung diseases now from exposure that occurred 30 or even more than 40 years ago. There can be a lag period of 20 years or more after exposure to asbestos before symptoms of lung disease appear. Currently about 500 men and 100 women develop mesothelioma in Australia each year. Australia and the UK have the highest rates of asbestos-related death in the world. ![]() Inhaling the fibres can cause a fibrous stiffening and shrinking of the lung, as well as lung cancer, particularly the incurable, rapidly-growing lung cancer known as mesothelioma.Īsbestos-related disease has killed thousands of Australians. Asbestos was gradually phased out after 1980 and was prohibited completely after 31 December 2003.Īsbestos fibres are so tiny they can be inhaled deeply into the lungs where they become embedded and cause a range of lung diseases, that are slow to develop but in many cases deadly. Depending on how old it is, fibro contains mixtures of blue (crocidolite), brown (amosite), and white (chrysotile) asbestos fibres.
