Mesothelioma is an extremely malignant and incurable cancer that infects the membrane that surrounds most of the internal organs.
Mesothelioma is also a very subtle form of cancer, with few noticeable symptoms until the disease is extremely advanced. Unfortunately, this is what makes mesothelioma so deadly; by the time the symptoms are noticeable they are virtually impossible to treat. The cancerous tumors are so entrenched in the lungs, gastrointestinal tract, or heart, that no amount of chemotherapy, radiation, or surgery will completely eliminate them.
Pleural mesothelioma represents 75% of mesothelioma cases - but it is far from the only type of this deadly cancer. Peritoneal mesothelioma affects the lining around the stomach and intestines, and is just as dangerous and deadly.
