Types of Malignant Mesothelioma
- The first type of malignant mesothelioma is called pleural mesothelioma or pleural mesothelioma of the. This is the most common type of mesothelioma, about 75% of all mesothelioma cases are caused by this type. Pleura is a thin serous membrane is found between the lungs and chest cavity which provides a lubricated surface prevents the lungs from rubbing against the chest wall. It also serves as a protective wall.
- The second type of mesothelioma is Peritoneal Mesothelioma, otherwise known as mesothelioma of the peritoneum. The peritoneum is a thin serous membrane that encloses the abdominal organs. Peritoneal Mesothelioma is a form or type of malignant mesothelioma cancer is rare. This disease accounts for about 10% to 20% of all mesothelioma cases. These tend to be more invasive form of cancer, patients who have been diagnosed with this disease have a shorter life expectancy than if they were diagnosed with Pleural Mesothelioma.
- The third types of mesothelioma is pericardial mesothelioma or better known as mesothelioma of the pericardium. This species is a common type of mesothelioma and this type accounted for less than 10% of all mesothelioma cases. Pericardium (heart sac) is a serous membrane that surrounds and protects the heart.
There are about 2,200 new cases of malignant pleural mesothelioma each year visceral. Mesothelioma is difficult to diagnose mesothelioma is rare and treatable. The most common symptoms are dyspnea and chest wall pain.
Cause
The main cause of malignant mesothelioma of the visceral pleural is Asbestos. The period between exposure to asbestos and the onset of symptoms is approximately 20 to 50 years. Because of this late onset, it occurs most often in later years of life. It also occurs more frequently in men than in women.
Diagnosis
Doctors usually make an incision through the chest wall and insert an instrument called a thoracoscope between two ribs to see the area. The doctor will then perform a biopsy to select a sample of tissue can be analyzed under a microscope.

Mesothelioma Stages
- Stage I: Cancer is found in the lining of the chest cavity near the lung and the diaphragm or the heart or lungs.
- Stage II: Cancer has spread beyond the chest lining to lymph nodes in the chest.
- Stage III: Cancer has spread to the chest wall, center of the chest, heart, through the diaphragm, or stomach lining, and in some cases into nearby lymph nodes.
- Stage IV: Cancer has spread to distant organs or tissues.
Radiation and radiotherapy are used in situations where the cancer is localized at the origin. Chemotherapy is used in more advanced stages of malignant mesothelioma.
Cytoreductive surgery plus hyperthermic (heated) chemotherapy improves survival and quality of life for patients with peritoneal metastases (tumors involving the stomach lining).
Surgery is an option that is used for Stage I malignant mesothelioma. For stage II to IV, treatment with surgery are still evolving.
