Mesothelioma (benign-fibrous)
Definition
Benign mesothelioma is a noncancerous tumor of the pleura (lining of the lung and chest cavity).
Causes
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.
Symptoms
- Chronic cough
- Shortness of breath
- Chest pain
Approximately half of mesothelioma patients are asymptomatic (show no symptoms of disease).
Exams and Tests
During a physical examination, the health care provider may notice a clubbed appearance of the fingers.
Tests that may show mesothelioma include the following:
Treatment
Surgery is usually necessary for a solitary tumor.
Outlook (Prognosis)
The outcome is expected to be good with prompt treatment. The condition may return in about 1 out of 10 cases. It may reoccur as long as 10 years later.
Possible Complications
Pleural effusion (fluid escaping into the membranes around the lungs) is a complication.
When to Contact a Medical Professional
Call for an appointment with your health care provider if you notice symptoms of mesothelioma.
