Mesothelioma is a form of cancer that is almost always caused by exposuring by asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers body's internal organs at large field. Its most common site is the pleura (outer lining of the lungs and chest cavity), but it may also occur in the peritoneum (the lining of the abdominal cavity) or the pericardium (a sac that surrounds the heart) too.

Most people who develop mesothelioma have worked on jobs mostly where they inhaled asbestos particles, or have been exposed to asbestos dust and fibre in other mean, such as by washing the clothes of a family member who worked with asbestos. Unlike lung cancer, there is no association between mesothelioma and smoking.

The symptoms of mesothelioma at early stage are generally non-specific, and may lead to a delay in diagnosis. Sometimes resembling viral pneumonia, pleural mesothelioma patients may present with shortness of breath, chest pain and/or persistent cough, in some case some patients show no symptoms. Common symptoms of pleural mesothelioma at less condition include fever, night sweats and weight loss. But Symptoms of peritoneal mesothelioma may include pain or swelling in the abdomen because a build-up of fluid, nausea, anemia or swelling of the feet, bowel obstruction, weight loss.

Causes of Mesothelioma:

Asbestos is a fiber that occur normally can enter the lungs or stomach when they are not handled properly or with careless. When asbestos-containing materials or equipment are disturbed, friable asbestos fibers are released into the air, then asbestos fibres went to the lining of the stomach or lungs.

Basically mesothelium provides lubrication and protection for the movement of organs. Once inside, the body is unable to break down asbestos fibers, leaving the fibers deposited in the mesothelium where they eventually cause its cells to divide. After a long period cancer starts in the mesothelium causing shortness of breath and coughing, which are the most frequent causes of hospitalization.
