Pericardial Mesothelioma is also known as cancer tissue sac containing the heart.

Symptoms may include chest pain and breathing problems. The tumor and / or fluids that accumulate between the heart and the sac can compress the heart, causing breathing problems. Your doctor may diagnose this cancer using a procedure called thorascopy for thoracoscopy, which might in turn require a cut in the chest cavity to remove the tumor.

Patients who develop an excessive amount of fluid around the heart, called an effusion, may be diagnosed with mesothelioma of the pericardium through a sample of fluid. It is also possible to drain the fluid to relieve symptoms of mesothelioma of the pericardium. The process of drainage of these fluids is known as pericardiocentesis.
