Biphasic mesothelioma refers to a cell structure associated with malignant mesothelioma tumor cells. Among mesothelioma cancer cells, they are generally divided into two subcategories. Epithelioid mesothelioma cells are the most common type, accounting for approximately 80% of all malignant mesothelioma cells. Sarcomatoid mesothelioma cells are far rarer, accounting for just 10-15% of malignant mesothelioma cells. Biphasic mesothelioma cancers are those which comprise a combination of the two aforementioned malignant cells types.
Epithelioid mesothelioma malignant cells have a clearly defined tubular structure. Upon intense magnification, the cell structure is clearly visible, including a distinguishable nucleus. Sarcomatoid mesothelioma malignant cells are clearly different than epithelioid cells, with their oval shape being clearly distinguishable from their counterpart. Upon intense magnification, the cell structure is loosely visible while the nucleus is often muddled and difficult to distinguish.
Mesothelioma of all cell types, including biphasic, sarcomatoid, and epithelioid is an aggressive malignancy associated with rapid spread and poor prognosis. Mesothelioma is known only to be caused by asbestos exposure. Asbestos is a fibrous but durable and natural mineral. For many years asbestos was a key component for its fire-retardant properties in thousands of industrial products, including insulation, drywall, joint compound, and others.
Records now indicate that most manufacturers of products made with asbestos were well aware of the potential hazards posed by their products to their employees and those who utilized the materials. Asbestos products could be found nearly anywhere, including industrial jobsites, naval shipyards, and construction sites, thereby endangering hundreds of thousands of people in the process. If you or a loved one has been exposed to asbestos or diagnosed with mesothelioma or other asbestos related health disorder, we urge you to complete the brief form on this page and we’ll be pleased to rush you a complimentary mesothelioma and asbestos exposure information packet. Find out about top doctors, mesothelioma treatments, and financial compensation opportunities for those wrongfully exposed.
