Mesothelioma is an aggressive cancer
Malignant mesothelioma is the most serious of all asbestos-related diseases. Although rare, mesothelioma, cancer is no longer considered rare. The main cause and risk factor for mesothelioma is asbestos.
A correct diagnosis of mesothelioma is very difficult for doctors, because the disease often with symptoms that mimic other common diseases. There is no known cure for mesothelioma, but treatments such as surgery and chemotherapy have improved the prognosis of mesothelioma typical.
Pleural mesothelioma (affecting the lungs, the protective lining of the chest cavity) is about three quarters of all mesothelioma incidence. Peritoneal mesothelioma affects the abdominal cavity and pericardial mesothelioma, which affects the heart chamber, constitute the rest. Testicular cancer, mesothelioma is extremely rare and is usually presented with peritoneal metastasis of diversity. There are three types of mesothelioma cells recognized. Between 50 and 70% of cases of mesothelioma of the epithelial variety. Although the prognosis is generally poor, there will be less aggressive than the sarcomatoid mesothelioma and biphasic mesothelioma, which comprise the remaining diagnoses cell type.
The cavities within the body including the breast, stomach, heart, and are surrounded by a membrane of cells known mesothelium. Mesothelial cells in general to support organ function. The mesothelium is particularly important in organs that are often moving, such as the expansion or contraction of the lungs, stomach or heart. The lubrication of mesothelial cells allows free movement within the body. The mesothelium of the chest, abdomen, and heart chambers are the pleura, peritoneum and pericardium, respectively. Each of these groups of mesothelial cells are extremely critical for the functions of body structures that compose them.
Malignancies (cancerous tumors) that are membranes in mesothelial cells as malignant mesothelioma, mesothelioma, or simply unknown. Benign tumors of the mesothelium are known to occur, but are much rarer than the most common malignant cancer.
Although tumors of the mesothelium were the first to the late 18th century realized it was not until the mid 20th century century, that this cancer has been studied in more detail. It was at that time, the suspicion of cancer, the causal relationship with asbestos exposure were more substantiated. A research joint venture by the Department of Thoracic Surgery at the University of Witswater and / Johannesburg General Hospital in South Africa has provided the most convincing evidence of the relationship between asbestos exposure and the development of pleural mesothelioma.
The incidence of mesothelioma is still quite rare, with only 2500 to 3000 diagnoses in the United States each year. There was an increase in diagnoses reported 1970-1984, based on the latency period between diagnosis and the level of radiation exposure, which is about 40-60 years were assigned to have occurred before that date. The exhibition was common in almost all industries, but was particularly common in World War II era of the military-industrial cycle, including shipyards.
Although this cancer is more common in men over the age of 60 (largely due to industrial exposure to male-dominated industries) mesothelioma in women and children, as has been well described. Mesothelioma causes for diagnosis in women and children are mainly due to secondary exposure to asbestos, because it was not uncommon for men to return to asbestos in the house on his body or clothing when was the appropriate cleaning facilities are not on the site.
