Mesothelioma Cancer

Mesothelioma is a rare form of cancer that attacks cells, called mesothelial cells that make up membrane lining in the chest and abdominal cavity. The tissue called mesothelium, which is formed by

the mesothelial cells, help protects the organs by producing a lubricating fluid that allows the organs to move without irritating nerves. Almost always mesothelioma is caused by exposure to asbestos but some researchers believe the virus SV40 can also be a factor. While mesothelioma affects the lungs, it is not a lung cancer. Smokers are at risk for lung cancer, which in effect could lead to contracting other asbestos-related diseases. Lung cancer is more common and arises in the lungas inner tissues opposed to mesothelioma, which develops in the tissue that covers the lung.

Pleural Mesothelioma & Peritoneal Mesothelioma

Mesothelioma is most commonly located in the pleural and peritoneal regions of asbestos exposed workers. Pleural mesothelioma is cancer of the pleura, the membrane that lines the lungs and chest cavity. Peritoneal mesothelioma is cancer of the peritoneum, the lining of the abdomen. Pleural mesothelioma can usually be diagnosed earlier than peritoneal mesothelioma. Both pleural and peritoneal cancer involves serosal membranes, which are delicate membranes composed of connective tissue. Mesothelioma normally begins in the lungs and spread to the abdominal lining, which worsens the condition. The invasive nature of the tumor on heart and lungs are usually the ending factor in the patient.

Malignant Mesothelioma

Malignant mesothelioma is rare and seldom curable. Those with malignant mesothelioma are expected to live just two years at the most. Patients who do not receive any treatment have a median survival rate of 4-12 months. Those who do receive treatment can prolong the span of their life.
