Malignant cancer that occurs in the mesothelial membrane known as malignant mesothelioma, or just mesothelioma. benign tumor of the mesothelium is known to occur, but less frequently than the more common mesothelioma cancer. While the mesothelium tumor was first discovered in the late 18th century, not until the mid-20th century cancer was studied in detail. Cancer is suspected of stemming from exposure to asbestos. A joint study from the Department of Thoracic Surgery at the University Witswaterand / Johannesburg General Hospital in South Africa provide evidence of the most interesting and the relationship between exposure to asbestos and the development of pleural mesothelioma.
The incidence of mesothelioma is still quite rare, with only 2.500 to 3000 diagnoses in the United States each year. There is a surge in diagnoses reported between 1970 and 1984, which has been associated with the latency period between diagnosis and high-exposure industries that occurred approximately 40-60 years before present. virtually all industries to be the cause of frequent disease mesothelioma.
Although this cancer is more commonly infect men over the age of 60 (mostly caused by industrial exposure in the industry dominated by men), this may occur also in women and children. Mesothelioma Causes women and children are mainly caused by exposure to asbestos.
There are three types of mesothelioma cells. Between 50 and 70% of all mesotheliomas are of epithelial type. While the prognosis is less aggressive than mesotheliomas of the sarcomatoid and biphasic range, which consists of the remaining diagnoses. Mesothelioma treatment options for each type of diagnosis is basically the same, depending on the stage at diagnosis and overall patient health.
pleural mesothelioma (affecting the protective layer of the lungs in the chest cavity), representing about three-quarters of all incidents of mesothelioma. Peritoneal and pericardial mesotheliomas, affects the abdominal cavity and the heart made up the rest. testicular mesothelioma is rare and usually presents with metastases from various peritoneal.
