A noncancerous tumor of the pleura (lining of the lung and chest cavity).
Causes, incidence, and risk factors:
Nonmalignant mesothelioma is usually a localized tumor that affects men more frequently than women. The tumor may grow to a large size and compress the lung, causing the symptoms of shortness of breath.
Signs and tests:
A physical examination reveals the clubbed appearance of the fingers.
Tests that may show benign mesothelioma:
Surgery is indicated for a solitary tumor.
The outcome is expected to be good with prompt treatment.
Pleural effusion (fluid escaping into the membranes around the lungs) is a complication.
Calling your health care provider:
Call for an appointment with your health care provider if you notice a chroniccough or other signs of mesothelioma.
