Pleural mesothelioma, also known as mesothelioma of the pleura, is a tumor of the lining surrounding the lungs. The pleura is a thin tissue around the lungs and the inside of the chest. In order to protect the lungs, the pleura produces a small amount of fluid which helps cushion the lungs, making the lungs move more smoothly during breathing.

Benign (Non-Cancerous) pleural mesothelioma

Benign pleural mesothelioma is a non-cancerous tumor that has not spread to other organs of the body. If the tumor is large, it may squeeze the lung itself and cause shortness of breath and pain.

Malignant Pleural Mesothelioma

Malignant Pleural mesothelioma is cancerous and can spread to other parts of the body. This rare form of cancer is found in the pleural sac lining of the lung. Exposure to asbestos is considered the primary cause of pleural mesothelioma.

Symptoms

Pleural mesothelioma may include shortness of breath, chest pain, back pain, pain in the rib cage, fluid build-up in the lung lining, hoarseness, coughing up blood, swelling of the face and arms, muscle weakness, paralysis and sensory loss.
