Asbestos-Related Diseases

Exposure to asbestos can cause not only pleural mesothelioma and other cancers, and severe scarring in the lungs and the disease known as asbestosis. This disease, not cancer, can still seriously affect the life of the victim, causing severe symptoms and means that you need for treatment. Some conditions, such as plaques and pleural effusion, which is usually present in most cases of pleural mesothelioma.
And pleural plaques

Pleural plaques are similar to scars in the lung pleura caused by collagen deposits. This plaque is formed as a result of exposure to asbestos. The plaques usually do not produce obvious symptoms. In addition, they can not be regarded as the beginning of cancer.
According to the Center for Disease Control and Prevention, about 50 percent of all people who are regularly exposed to asbestos develop pleural plaques. Because they do not carry any different symptoms, they often found during X-ray or CT scan done for some other reason, or those that are found during routine screenings that many people are exposed to asbestos to participate in an annual basis. Although the plaque does not show cancer, the patient's doctor may still want to order additional tests.
Exposure to asbestos can also cause pleurisy, which is a buildup of fluid between the layers of the parietal and visceral pleura. This fluid can cause pain and make it very difficult to breathe. If someone is determined that the fluid in the pleura, the doctor will probably order it to test the cancer cells. In addition, the fluid can be removed to relieve the unpleasant symptoms it causes.
Asbestosis
The first is called in 1928, asbestosis disease common in people with asbestos exposure. It is characterized by inflammation, scarring, and lung capacity is reduced. As in the latency period associated with pleural mesothelioma, the symptoms can take anywhere from 10 to 30 years to appear long after exposure has occurred in some cases.
The most common symptoms of asbestosis pulmonary fibrosis, defined as thickening or scarring of the lungs. Thus, the lungs are frozen, making it difficult for them to expand and contract. Other symptoms of asbestosis include:
Shortness of breath, especially during physical activity. Later this can expand dyspnea at rest.
Less tolerance for physical activity.
Pain or discomfort in the chest
Cough production of sputum
Finger clubbing (in some cases)
Symptoms of asbestosis can be easily confused with lung disease is more common, including asthma. That is why frequent misdiagnosis. Symptoms of asbestosis, however, developed over a long period of time, which makes it different from many other related lung diseases. Anyone who suspects that may have asbestosis must inform your doctor about your history with asbestos.
How to develop asbestosis?
Asbestosis occurs when a person inhaling small, sharp asbestos fibers. These fibers can become lodged in the lungs and can eventually cause scarring and stiffness. After inhaling asbestos fibers is difficult to remove, and even body macrophages, which is interesting and can ingest foreign substances, have trouble against asbestos fibers. As a result, the cumulative scars air sacs (alveoli), which causes shortness of breath, as lung volume decreases. It will also take a more muscular effort to breathe, rather than people with normal lungs.
Asbestosis and asbestos
Not all people who suffer from asbestos exposure developed asbestosis. However, reports have shown that people who experience moderate to severe exposure to asbestos in the past ten years or more are at significantly higher risk of developing these and other asbestos-related diseases. Asbestos miners particularly vulnerable.
It usually takes 10 years after the first exposure to asbestos to develop individual asbestosis. However, in recent cases of asbestosis among emergency workers who responded to the attacks on 9-11, it is evident that the disease may progress more rapidly if the exposure under intense level.
Smoking does not cause asbestosis but can worsen the condition. There is also evidence that people with asbestosis who smoke are more likely to develop lung cancer because of their smoking habit. Smoking does not increase the risk of pleural mesothelioma, but this is a compromise of light, making them more susceptible to disease.
Tests on Asbestosis
Patients who suspect they may be developed asbestosis must provide their physician with a history of thorough professionals, so that the relationship between inhaled asbestos and clear so that the physician can order appropriate tests to confirm or refute the diagnosis.
In the first test of Asbestos, a doctor can listen to the lungs. The lungs are affected by asbestosis often produce very dry, crisp sound. However, it is not sufficient for diagnosis. Most likely, your doctor may prescribe some test images, ranging from simple chest x-rays to CT scans or MRI. It can also serve as a test lung to determine how well the lungs.
Asbestosis Treatment
There is no cure for asbestosis. Instead, your doctor will be aimed at reducing the symptoms and make sure no progress. As mentioned earlier, is very important for all victims of asbestosis who smoke to quit smoking immediately. Patients must wear oxygen to aid breathing and the doctors can offer the flu or pneumonia vaccines to prevent respiratory tract infections, which can lead to further complications. Blood-thinning medications can also be proposed in order to prevent blood clots from forming and prevent the vessels are narrowed. In some cases, lung transplant surgery will be offered.
Complications of Asbestosis
Common complication of asbestosis include:
Pulmonary hypertension - high blood pressure in the pulmonary artery
Lung cancer, smokers and asbestosis are at high risk of developing cancer.
Pleural mesothelioma - cancer is known to develop in those with asbestosis.
Heart problems - pulmonary hypertension caused by asbestosis may lead to the expansion of the right ventricle of the heart and, ultimately, failure.
All these conditions can be life threatening, so patients should be careful to monitor their overall health because they had asbestosis.
