Mesothelioma is a rare form of cancer almost exclusively caused by exposure to asbestos. Pleural mesothelioma is the most common type of mesothelioma, a rare cancer that develops in the mesothelial cells that make up the mesothelium, the membrane that covers most of the organs and body cavities. In the case of pleural mesothelioma, cancer develops in the lining of the lungs, pleura or pleural membrane.
Pleural mesothelioma accounts for most cases of mesothelioma, about two thirds of cases diagnosed. Pleural mesothelioma usually develops in a single layer, but it can metastasize, or spread, to another layer. As with other types of mesothelioma, pleural mesothelioma is difficult to diagnose because symptoms often do not emerge for some time after initial exposure to asbestos.
Like all cancers, mesothelioma, pleural mesothelioma is caused by exposure to asbestos occurs when toxic asbestos fibers are trapped in the spaces between mesothelial cells. Once trapped in the body, asbestos fibers cause cancer cells to divide abnormally, causing thickening of the membrane layer and pleural mesothelial cells, causing an accumulation of fluid (called effusion).
In case of pleural mesothelioma, asbestos exposure is by inhalation of asbestos fibers. In addition, pleural mesothelioma is sometimes called a lung cancer to asbestos. These asbestos fibers are embedded in the lining of the lungs (the pleura). Over time, causing chronic inflammation that ultimately leads to growth of cancerous tumors or, in some cases, asbestosis.
Pleural mesothelioma patients is not diagnosed in time for curative treatment have fewer treatment options are mainly limited to palliative treatments, designed to relieve pain and discomfort to improve the quality of life for patients, rather than prognosis.
Patients with pleural mesothelioma shows the three types of mesothelioma cancer cells, epithelioid mesothelioma, mesothelioma sarcomatoid mesothelioma and biphasic.
Pleural plaques are localized scarring (fibrosis), composed of deposits of collagen fibers formed as a result of exposure to asbestos. Pleural plaques first appear around 20 years after a person is exposed to asbestos. Pleural plaques can develop even at low dose, intermittent exposure. Pleural mesothelioma symptoms are nonspecific and may indicate other less serious conditions.
Since pleural mesothelioma is the most common form of cancer, more research and knowledge on this type of mesothelioma appears to use when detailing a treatment plan. Description of treatment options available is often very important for patients and their families.
Usually, patients receive a combination of two or more of these types of treatment. Early detection of pleural mesothelioma can improve the prognosis of a patient with mesothelioma considerably, and these patients have more extensive treatment options. Patients diagnosed with pleural mesothelioma in a phase or two usually have more options for treatment and prognosis.
Palliative treatments include the removal of the pleural space, and surgical removal of the tumor to relieve pressure in the lungs. Radiotherapy and chemotherapy are common treatment options for mesothelioma. A variety of mesothelioma treatments are available new and original, and a variety of clinical trials. While the prognosis of patients with pleural mesothelioma is usually between four and 18 months, there are several methods of traditional and alternative treatment that can prolong the life expectancy of the patient.
The survival rate was also affected by the type of mesothelioma cancer cells, patients with other types of cells have the shortest life expectancy biphasic. However, pleural plaques are almost always present in patients with asbestosis and are often present in patients with mesothelioma. The survival rate at five years for patients with mesothelioma is about 10 percent. Once diagnosed with mesothelioma, it is important that patients maintain good eating habits to help fight the disease.
Many patients die within six months after diagnosis, some may last up to one year, but few survive beyond this period. There is no cure for mesothelioma in any of their rankings, almost all patients receive some type of mesothelioma treatment to extend life expectancy and reduce discomfort.
