Mesothelioma is a rare form of cancer tumors, known as the mesothelium of body tissue. The mesothelium is a layer of specialized cells to protect the line and many internal organs, such as the chest and abdominal cavity.
Types of malignant mesothelioma
The first type of malignant mesothelioma is called pleural mesothelioma, or mesothelioma of the pleura. And 'the most common type of> Mesothelioma, of whom about 75% of all cases of mesothelioma is. The pleura is a thin serous membrane between the lungs and chest, has a lubricated surface that prevents the lungs from rubbing against the chest wall requires. It also functions as a protective layer.
The second most common type of mesothelioma, peritoneal mesothelioma, also known as mesothelioma of the peritoneum. The peritoneum is a thin serous membrane that encloses organs. Peritoneal Mesothelioma is a rare form of malignant mesothelioma cancer. This disease represents approximately 10% to 20% of all mesothelioma cases. Rather it is a more invasive form of cancer, patients diagnosed with this disease have a life expectancy shorter than that which would attract pleural mesothelioma.
The third and least common type of mesothelioma, pericardial mesothelioma, also known as> Mesothelioma of the pericardium. Accounts for less than 10% of all mesothelioma cases. The pericardium (pericardial sac) is the serous membrane that surrounds and protects the heart.
There are about 2,200 new cases of malignant mesothelioma of the visceral pleura of each year. Mesothelioma is difficult to diagnose and is rarely curable. The most common symptoms are dyspnea and chest pain.
CAUSE
Asbestos is the main causemalignant mesothelioma of the visceral pleura. The period between the time of exposure to asbestos and the onset of symptoms is about 20 to 50 years. Because of this delay, which occurs more frequently in recent years. It is also more common 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 on the range. The doctors then a biopsySelect a sample of tissue that can be analyzed under the microscope.
Stages of mesothelioma
Phase I: the tumor is in the lining of the chest cavity near the heart or lungs and the diaphragm or the lung.
Stage II: Cancer has spread through the lining of the chest to lymph nodes in the chest.
Phase III: the cancer has spread into the chest wall, the center of the chest, the spread of the heart, through the diaphragm or abdominal lining, and in some cases, closeLymph nodes.
Stage IV: The cancer has spread to distant organs or tissues.
Treatment
Radiation therapy and radiation therapy in situations where the tumor is localized at the time of creation.
The chemotherapy used in advanced stages of malignant mesothelioma.
Cytoreductive surgery plus hyperthermia (heating) Chemotherapy improves survival and quality of life of patients with peritoneal metastases (tumors, the lining ofAbdomen).
Surgery is used to select for stage I malignant mesothelioma. For stages II-IV, treatment with surgery is constantly evolving.
