Epithelioid mesothelioma is the most common type of malignant mesothelioma cell type, accounting for 50-70% of all mesotheliomas. Individual cells are known to be relatively uniform in shape and with a uniquely “tubular” appearance. When the cell is viewed under intense magnification, the cell nuclei is known to be distinctly distinguishable from other cell nuclei.
Other cancer cell types, such as adenocarcinomas, however, have been known to take similar shape and are often misclassified. Adenocarcinomas are cancer cells that can also occur within the mesothelium, but cannot originate within this membrane. Typically adenocarcinomas will originate within more internal tissue before sufacing within the mesothelium.
Mesothelioma is a rare malignancy known only to be caused by exposure to asbestos. Asbestos is a naturally occurring but fibrous and durable mineral that was used for many years as an industrial insulation compound. Asbestos fibers, when inhaled easily become lodged in mesothelial tissue, causing inflammation and internal irritation. This inflammation lays the foundation for plaques upon the mesothelium surface and eventually malignant cells.
Mesothelioma is a rare but aggressive cancer and is often difficult to diagnose. Records now show that asbestos manufacturers were fully aware of the hazards which asbestos posed and continued to manufacture their harmful products. If your or a loved one has been diagnosed with mesothelioma and believe you may have been exposed to asbestos, we urge you to complete the brief form on this page. We’ll send you a free mesothelioma and asbestos exposure information packet, detailing top treatments, new therapies, and information on how to obtain financial compensation for asbestos related injuries.
