How does Biphasic Mesothelioma Form?
Like other forms of mesothelioma, biphasic mesothelioma overwhelmingly begins with asbestos exposure. When a person develops mesothelioma, the cancer cells can be classified as either epithelioid cells or sarcomatoid cells. They are both deadly and are distinguished by their shape and the appearance of the nucleus. When a person has both epithelioid and sarcomatoid cells present in their tumor(s), either mixed together or epithelioid in one area of the tumor and sarcomatoid in another area, the type of mesothelioma is called biphasic.
