There are four types of mesothelioma. Each indicates that the disease is growing in a specific part of the body.
Pleural mesothelioma – develops in the mesothelium that covers the lungs.
Peritoneal mesothelioma – develops in the mesothelium which lines the stomach.
Mesothelioma pericardial – develops in the mesothelium that covers the heart.
Mesothelioma testicular develops in the lining of the testicles.
More than 75% of the patients diagnosed with mesothelioma suffer from the type pleural. The peritoneal mesothelioma is the second most common and accounts for between 10 and 20 per cent of the cases, while mesothelioma, pericardial and testicular are only 1 percent of the diagnoses.
The cancer of mesothelioma can also be classified by the type of cell. There are three types of cells that line the mesothelium and cancer mesothelioma can develop in any of them. The types of mesothelioma cell include:
Mesothelioma epithelial – develops in cells small enough for the membrane, very similar to a tube.
Mesothelioma of the sarcomatoid – develops in the cells of the membranes long – similar to an axle.
Mesothelioma biphasic – it develops in the epithelial cells and sarcomatoideales.
