Mesothelioma is a form of lung cancer involving the mesothelium, which is the lining around the lungs. Mesothelioma, which often is linked to the inhalation of asbestos, can also occur in the lining around the heart or in the abdomen.
Incidence
Mesothelioma is considered rare, according to the National Cancer Institute. Approximately 2,000 cases are diagnosed annually in the United States. Men are at higher risk for developing mesothelioma.
Exposure
Commonly exposed workers include miners, shipyard workers and workers in the heating and cooling industry. Others who may have a higher-than-average risk are electricians, plumbers, welders, boiler makers, railroad workers, pipefitters and auto mechanics.
Diagnosis
The first step in diagnosing mesothelioma is a CT scan or MRI. If a tumor is found, a biopsy is performed to determine whether it is mesothelioma.
Treatment
Chemotherapy is commonly used to treat mesothelioma. It is also treated with surgery and radiation.
Survival Rates
The American Cancer Society reports that only about 10 percent of patients diagnosed with mesothelioma will survive five years or longer after the initial diagnosis.
Symptoms
Symptoms of mesothelioma include cough, coughing up blood, night sweats, fatigue, weight loss, pain and difficulty swallowing.
