Mesothelioma cancer refers to a type of cancer resulting from exposure to asbestos. Asbestos is a type of mineral that is often used for insulation in many homes and other infrastructures in various industries. Once the person inhales asbestos, the mesothelium of the lungs is seriously and irreversibly damaged.
The mesothelium refers to the lining of the lungs that helps protect the organ from various infections. Although it is capable of protecting the outer portion of the lungs, asbestos fibers can damage the lining in time, thereby causing cancer.
