Mesothelioma is a type of cancer.

Mesothelioma is a type of cancer affecting the mesothelial lining cells in the chest and the abdomen. Mesothelioma is rare, although it seems to be rising. Approximately 2 000 to 3 000 new cases of mesothelioma are diagnosed each year in the United States only. For both types of mesothelioma symptoms are not only specific to this disease and will often diagnosed or misdiagnosed for a considerable time. The plague, difficulty breathing, abdominal and chest pain can all be attributed to other causes, so this cancer has quite fair ahead of time before the diagnosis usually occurs. Because of the difficulty of diagnosing mesothelioma survival after diagnostic time is estimated at approximately one year.

There are two main types of mesothelioma.The first type, pleural mesothelioma, spreads into the chest cavity, sometimes involves the type poumons.Ce or cancer metastases may in any of the organs of the body, including the brain.

Metastasis occurs more often that believed it and report the progress of the disease. Pleural mesothelioma symptoms are persistent pain in the chest and serious difficulty breathing caused
by pleural effusion or an accumulation of fluid in the mucosa pleural cough, weight loss and fever are also common symptoms. For this type of mesothelioma survival time is better than that of Peritoneal Mesothelioma. The median survival time is 17 months, with 10% of patients living for three years after diagnosis.

The second type of mesothelioma is peritoneal cancer mésothéliome.Ce invades the abdominal cavity, liver, spleen and sometimes the intestine. The predominant symptoms of Peritoneal Mesothelioma include persistent pain region thus a swollen abdomen, both because of the accumulation of fluid in the abdomen and the bodies concerned. Other symptoms include nausea, vomiting and swelling of the feet, foot, and difficulty in moving the intestines. Peritoneal Mesothelioma prognosis is worse than pleural mesothelioma, with a median survival time of ten months after diagnosis.

Mesothelioma takes two more rare forms.Benign mesothelioma is a cancer of the peritoneum péritoine.Le mesothelioma is the coating of the principal organs in the chest and the abdomen. It is difficult to diagnose, and appears most often in young women. The pericardium mesothelioma is a rare heart cancer. Mesothelioma can also occur in the ovaries and the scrotum. The benign, these unusual types of mesothelioma in mesothelioma prognosis is very low.

The progress of mesothelioma is broken up to four steps. These steps are planning to predict how far along the cancer has spread. Staging is based on tomodensitométriques, x-rays and MRI Imaging.Decisions concerning treatment and prognosis depend on phase of mesothelioma, as well as the nature if mésothéliome.Dans step, mesothelioma is present in the pleura, lung, pericardium or diaphragm and is localized on one side of the body. Mesothelioma invades the chest wall or the esophagus in the second step.The second step may also see cancer in the core, on both sides of the pleura or the lymph nodes in the chest.The third step involves penetration by the diaphragm and the peritoneum and sees cancer spread to more distant lymph nodes.The fourth and last step occurs when the tests provide proof of metastases in the distant organs.In the fourth phase, mesothelioma spread through the bloodstream to these new monuments.

Mesothelioma is often caused by exposure to asbestos .the ' asbestos was frequently used for the insulation of houses or businesses.Military buildings, schools and factories have also been found to contain asbestos .rayonnement dioxide thorium may also cause mésothéliome.Ce material has been used for x-ray, but was not widely used during longtemps.Zéolithe, perhaps also related to asbestos, silicate material cause mesothelioma zeolite-induced mésothéliome.Cas centralize Anatoly Turkish area.
