Pleural Mesothelioma is a rare and aggressive cancer that affects the lining of the lungs, known as the pleura. It is primarily caused by exposure to asbestos, a naturally occurring mineral that was widely used in construction and manufacturing. Symptoms often include chest pain, shortness of breath, and persistent cough, which can make diagnosis challenging. The disease typically develops many years after exposure to asbestos, making early detection difficult. Treatment options may include surgery, chemotherapy, and radiation therapy, but the prognosis is often poor due to the advanced stage at which it is usually diagnosed.
