Malignant mesothelioma is an uncommon type of cancerous tumors originating from the body tissue known as the mesothelium. The mesothelium is the specialized layer of tissues that line and protect many internal organs like the chest and abdominal cavities.
# Types of Malignant Mesothelioma
- The first type of malignant mesothelioma known as Pleural Mesothelioma or mesothelioma in the pleura. It is the most popular type of mesothelioma creating up approximately 75% off mesothelioma cases. The pleura is any thin serous membrane discovered between the lungs and the chest cavity that offers a lubricated surface preventing the lungs from chafing against the chest walls. It also serves for a protective layer.
- The second most common type of mesothelioma is Peritoneal Mesothelioma, also known as mesothelioma in the peritoneum. The peritoneum is any thin serous membrane that encloses the organs in the abdomen. Peritoneal Mesothelioma is a rare type of malignant mesothelioma cancer. This disease accounts for approximately 10% to 20% off mesothelioma cases. It tends to be a more invasive form of cancer, patients diagnosed with this disease have a shorter life expectancy than whenever they had attracted Pleural Mesothelioma.
- The third and least common type of mesothelioma is pericardial mesothelioma also called mesothelioma of the pericardium. It accounts for under 10% of all mesothelioma cases. The pericardium is a serous membrane that surrounds and protects the heart.
There are about 2,200 new cases of malignant mesothelioma in the visceral pleura each 12 months. Mesothelioma is difficult to diagnose it is rarely curable. The most common symptoms are dyspnea and chest wall pain. Causes Asbestos is the predominant cause of malignant mesothelioma of the visceral pleura. The period between time of exposure to asbestos and the onset of symptoms is approximately 20 to 50 years. Because of this late onset, it occurs most commonly from the later years of life. It also occurs more often in men than in women.
# Diagnosis of Malignant Mesothelioma
Doctors usually make an incision in the chest wall and insert an instrument called a thoracoscope between two ribs to watch the area. Doctors will then do a biopsy to choose a tissue sample that can be analyzed under a microscope.
# Stages of Malignant Mesothelioma
Stage I: The cancer is found in the lining of the chest cavity near the lung and heart or in the diaphragm or the lung.
Stage II: The cancer has spread beyond the lining in the chest to lymph nodes from the chest.
Stage III: Cancer has spread into the chest wall, center of the chest, heart, through the diaphragm, or abdominal lining, and in some cases into nearby lymph nodes.
Stage IV: Cancer has spread to distant organs or tissues.
Treatment Radiation and radiotherapy are used in situations where the cancer is localized in the point of origin. Chemotherapy is used in more advanced stages of malignant mesotheliomas. Cytoreductive surgery plus hyperthermic (heated chemotherapy improves the survival and quality of life for patients with peritoneal metastases cancers involving the lining in the abdomen). Surgery is the method used for Stage I malignant mesothelioma. For stages II to IV, treatment by surgery continues to evolving.
