Of the 3,000 cases of mesothelioma each year, the rarest is mesothelioma of the heart called pericardial mesothelioma. The causes of pericardial mesothelioma is still not fully understood by scientists and doctors. Many scientists believe that asbestos is inhaled and ultimately makes its way to the blood stream however this is still very much a theory.
What is known is that asbestos fibers get stuck in the pericardial membranes of the heart. Over time, the accumalation of these asbestos fibers cause changes in the cells of the pericardium often resulting in cancer. Once these cells become cancerous, the divide and multiply rapidly. As these mesothelioma cells increase in quantity, the pericardial membranes thicken resulting in tumors. This build up puts pressure on the heart.
Since pericardial mesothelioma is so rare, it has been difficult for doctors to create a list of recognizable symptoms. The problem is that symptoms of pericardial mesothelioma resemble symptoms of other heart diseases. If any of the following symptoms are occuring, it is advised that one should seek medical attention as soon as possible. Only a number of specific tests can determine whether mesothelioma of the heart is apparent.
Symptoms of mesothelioma (pericardial mesothelioma) of the heart include:
Heart palpitations
Chest pain
Difficulty breathing (event at rest)
Fever
Night sweats
