- How do Emphysema and Black Lung Compare?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: You recently had an article on emphysema, that I found very
- interesting. A friend of mine has Black Lung and I would like to know how
- these two diseases compare or are different. Thank you for any information
- you have on this.
-

-
- ANSWER: This interesting condition received its name because of the color of
- the lungs found on post-mortem examination in patients with the disease. It
- is one of a number of similar conditions grouped together under the
- classification of Occupational Lung Disease. It is also known as Coal
- Workers' Pneumoconiosis (CWP) or "anthracosis". In this condition, coal dust
- is inhaled into the lungs where it becomes trapped, forming "coal macules"
- around the bronchi of the lungs. Coal is not one of the dusts that lead to
- the excessive formation of fibrotic or scar-like tissue in the lungs, and so
- the structure and function of lung tissue is not greatly disturbed. However
- in some cases the accumulation of the dust causes the bronchioles to dilate,
- giving rise to the name "focal dust emphysema;" but contrasted to the
- emphysema I discussed recently, this condition does not cause obstruction to
- the airflow, and does not involve the alveoli (grape like air sacs) of the
- lung. A complication of CWP that occurs in about 1 to 2 percent of miners is
- known as progressive massive fibrosis, and this condition can cause extensive
- lung damage and associated symptoms. In many cases, the disease is
- complicated by emphysema and obstructive lung disease from such causes as
- smoking. Another related disease known as "silicosis" is the result of
- breathing in particles of silica dust, and is seen in such industries as hard
- coal mining, lead, copper gold and silver mining, as well as foundries,
- pottery making, and sandstone and granite cutting. Fibrosis or scarring of
- the lung may be extensive and breathing problems, cough and sputum production
- are considerable. There are no cures for these diseases, and treatment is
- directed at improving the flow of air and reducing the amount of secretions
- that are present in the lung.
