When a person is exposed to asbestos, in many years that person may exhibit a variety of symptoms that are indicative of past exposure. Some of the signs of asbestos exposure are more serious than others. Probably the most serious of the consequences is pleural effusions.
The pleura, or lining of the chest cavity, has two layers. The inner layer covers the longs while the outer layer lines the rib cage and the diaphragm. Between these two layers, the body produces a fluid. This fluid acts like the oil in a car's engine. It allows the lungs to expand and contract smoothly which, in turn, allows a person to inhale and to exhale easily. Sometimes, the body produces too much of the fluid. When this happens, fluid can build up between the two layers of the pleura. When the build up occurs, it is referred to as a pleural effusion.
Pleural Mesothelioma
While not always harbingers of doom because they are frequently due to pneumonia, pleural effusions can also be a symptom of a variety of types of cancer. This side effect develops once cancer cells have spread into the pleura. When the cells migrate, they irritate the pleura and cause fluid to build up. The most common types of cancer to cause pleural effusions are lung cancer, breast cancer, ovarian cancer, lymphomas, and mesothelioma.
When fluid builds up in the pleura, it presses on the lungs. This makes it less easy for a person to breath since the lung is unable to expand to its full capacity due to the presence of the fluid. In some situations, the lung, or at least part of it, will collapse. When the lung collapses, the person is likely to become increasingly breathless, not only while active but also while resting. Chest pain and a cough might also develop.
Pleural effusions are typically detected through the use of a chest x-ray of an individual who is x-rayed while lying on his or her side. By the time a pleural effusion develops, a person has usually already developed mesothelioma. This is not always the case but it frequently is true. Mesothelioma is caused by exposure to asbestos. The tiny fibers get trapped in the lungs, irritating them to the point that scar tissue develops. Because the scar tissue is exposed to asbestos, it is not an exact replica of the previous tissues. This results in tumors developing.
