what is mesothelioma???

What causes mesothelioma?

Asbestos exposure is the main cause of mesothelioma. After these fibers are breathed in, they travel to the ends of small air passages and reach the pleura where they cause physical damage to mesothelial cells that may result in cancer. In addition, they also cause injury to lung cells that can result in lung cancer and/or asbestosis (replacement of lung tissue by scar tissue). If swallowed, these fibers can reach the abdominal cavity where they have a role in causing peritoneal mesothelioma.

Exposure to asbestos, though mostly occupational, can also be environmental, or familial by household contamination, through the work clothes of an asbestos worker for instance.

Beginning 15 years after the onset of exposure, about 6% of asbestos workers die of mesothelioma. In one study of asbestos insulation workers, the death rate from mesothelioma was 344 times higher than in the general population.

What are the signs and symptoms of mesothelioma?

Early symptoms of mesotheliomas are not specific to the disease. People often ignore them or mistake them for common, minor ailments. Most people with mesothelioma have symptoms for only 2 to 3 months before they are diagnosed. About one-fourth have symptoms for at least six months prior to their diagnosis.

Over half of patients with pleural mesothelioma have pain in the lower back or at the side of the chest. Many report shortness of breath. A smaller percentage have trouble swallowing, cough, fever, sweating, fatigue, and weight loss. Other symptoms include hoarseness, coughing up blood, swelling of the face and arms, muscle weakness, and sensory loss.

Symptoms of peritoneal mesothelioma include abdominal (belly) pain, weight loss, nausea, and vomiting. There may also be a hernia, fluid in the abdominal cavity or a mass in the abdomen.

A person with any of these symptoms who has been exposed to asbestos should see a doctor right away.
