Malignant mesothelioma is the most serious of all asbestos-related diseases. Exposure to asbestos is the cause and the main risk factor for mesothelioma.
Ask a correct mesothelioma diagnosis is particularly difficult for doctors because the disease often presents with symptoms that mimic other common ailments. Currently there is no known cure for mesothelioma, but treatments like surgery and chemotherapy, the prognosis of mesothelioma typical improve and increase their life expectancy.
The three main types of mesothelioma exist and differ mainly affected organs. Pleural mesothelioma (protective coating that affect the lungs in the chest cavity) represents about three quarters of the incidence of mesothelioma. Peritoneal mesothelioma affects the abdominal cavity, and pericardial mesothelioma, which affects the heart chamber, the remaining.

There are three recognized types of mesothelioma cells. Between 50% and 70% of all mesotheliomas are epithelial variety. Although the prognosis is generally poor, it is considered less aggressive than sarcomatoid mesothelioma and biphasic mesothelioma to include the rest of the type of diagnostic cell.
The cavities within the body of the chest, abdomen and heart are surrounded comprises a known form mesothelium cell membrane. Mesothelial cells generally the functions of organs in charge. The mesothelium is particularly important for bodies which are generally in motion, such as expansion or contraction of the lungs, stomach or the heart. Lubrication of mesothelial cells allows free movement within the body. The mesothelium of the chest cavity, abdomen and heart, pleura, peritoneum and pericardium or appointed. Each of these groups of mesothelial cells is extremely critical for the functions of the organism include structures.
Tumors (cancers) are in the mesothelial membranes are known as malignant mesothelioma, or simply mesothelioma. Benign tumors of the mesothelium are known to occur, but are much less common than malignant mesothelial tumors.
Although mesothelioma tumors were first recognized in the 18th century, it was the middle of the 20th century, not particularly close examined and tested this cancer. It was at this time when they are suspected of cancer causation by exposure to asbestos converted more information. A joint undertaking of research by the thoracic surgery department at the University General Hospital Witswater and Johannesburg in South Africa provided the most compelling evidence of the link between exposure to asbestos and the development of pleural mesothelioma .
The incidence of mesothelioma is still quite rare, with only 2500-3000 diagnoses in the United States each year. There was an increase in diagnoses 1970-1984, which was attributed between diagnosis and the height of the industrial exhibition, which occurred about 40-60 years before that date to latency. Although the exhibition was common in almost all sectors in the US, which was the time of World War II especially prevalent in the military industrial cycle, including shipyards.
Although this cancer is much more common in men over 60, mesothelioma has also documented among women and children. Mesothelioma causes for diagnosis in women and children are mainly due to secondary exposure to asbestos, as it was not uncommon for men to bring asbestos home in the body or clothing.
