Mesothelioma is a rare form of cancer in which malignant cells are found in the mesothelium, a protective sac that covers most of the body's internal organs. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles. Mesothelioma which is a cancer of the mesothelium is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or peritoneum. Mesothelioma is very uncommon cancer; about 2,000 new cases of mesothelioma are diagnosed in the United States each year. Mesothelioma occurs more often in men than in women and risk increases with age, but this disease can appear in either men or women at any age.

Risk factor for mesothelioma: Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, or they have been exposed to asbestos dust. Washing the clothes of a family member who worked with asbestos can also put a person at risk for developing mesothelioma. Most insulation material contains asbestos like-Insulation on pipes, Brakes and clutches, Boiler insulation, Roof, floor and ceiling sites. Sites-Industrial sites like power plan, paper mills, refineries etc.

Pleural Mesothelioma Symptoms: Pleural mesothelioma affects the lining of the chest. Symptoms of pleural mesothelioma may include: Pleural Mesothelioma: Shortness of breath, Difficulty swallowing, Coughing, Sweating, Fever, Weight loss, Fatigue, Swelling in the upper body, especially the face and arms, Lower back pain, Pain in the side of the chest, Muscle weakness. Peritoneal Mesothelioma: Stomach pain, Weight loss, Anemia, Fever, Blood clotting abnormalities, Nausea, Vomiting, Swollen belly, Bowel obstruction. Pericardial Mesothelioma: Heart palpitations, Chest pain, Shortness of breath, Persistent coughing.

Mesothelioma Treatment: Surgery- either by itself or used in combination with pre- and post-operative adjuvant therapies, has proved disappointing. A pleurectomy is the most common surgery, in which the lining of the chest is removed in mesothelioma. Less common is an extrapleural pneumonectomy in which the lung, lining of the inside of the chest, the hemi-diaphragm and the pericardium are removed. Radiation therapy- radiation is often given post-operatively as a consolidative treatment. The entire hemi-thorax is treated with radiation therapy, often given simultaneously with chemotherapy. The necessary radiation dose to treat mesothelioma that has not been surgically removed would be very toxic. Chemotherapy- Chemotherapy is defined as treatment of cancer using chemical substances .In mesothelioma cancers cells grows in the affected region. Using chemotherapy destroy the cancer cells by further multiplication. It destroys the cancer cells, to shrink the growth, and relief symptoms like pain which is very common in mesothelioma.
