Types of Mesothelioma
Mesothelioma is divided into three primary histological types:
- Epithelioid mesothelioma - Epithelioid mesothelioma constitutes approximately 50% to 70% of all malignant mesothelioma making it the most common type of mesothelioma.
- Sarcomatoid mesothelioma - Sarcomatoid mesothelioma is the least common type of mesothelioma accounting for about 10% to 15% of malignant mesothelioma.
- Mixed or Biphasic mesothelioma - As its name implies, Mixed or Biphasic mesothelioma is combination of the sarcomatoid and epithelioid types. Approximately 20% to 40% of the mesothelioma cancer cases fall into the biphasic category.
Mesothelioma develops in three major areas of the body:
- Pleura – the lining of the lung, resulting in pleural mesothelioma
- Peritoneum – the abdominal cavity, resulting in peritoneal mesothelioma
- Pericardium – the heart, resulting in pericardial mesothelioma
As malignant mesothelioma can be confused with other cancers, consider getting a second diagnostic evaluation from your physician or from a mesothelioma oncology specialist.
