3. Pericardial Mesothelioma
Pericardial mesothelioma is one of the rarest types of mesothelioma and is named after the initial location of the cancer, on the exterior lining of the heart known as the pericardium. Only about one percent of all mesothelioma patients develop pericardial mesothelioma, which occurs due to the accumulation of fluid in the spaces between the layers of the pericardium. The symptoms of the disease include irregular heartbeat, chest pain, difficulty breathing, coughing, night sweats or fever, and fatigue. In the case of pericardial mesothelioma, treatment is mostly based on palliative care to help ease the symptoms since the location is too close to the heart so makes surgical removal of the tumor too dangerous.
