What is Mesothelioma?

What is Mesothelioma? More precisely, malignant me-so-thel-i-o-ma, is a rare form of cancer that develops from cells of the mesothelium, the protective lining that covers many of the internal organs of the body. This disease is most commonly caused by exposure to asbestos.[1] The most common anatomical site for this rare form of cancer is the pleura (the outer lining of the lungs and internal chest wall), but it can also arise in the peritoneum (the lining of the abdominal cavity), the pericardium (the sac that surrounds the heart),[2] or the tunica vaginalis (a sac that surrounds the testis).

Most people who develop this rare type of cancer have worked in jobs such as miners where they inhaled or ingested asbestos fibers, or were exposed to airborne asbestos dust and fibers in other ways. Washing clothes of a family member who worked with asbestos also creates a risk for developing.[3]

Signs and symptoms include shortness of breath due to pleural effusion (fluid between the lung and the chest wall), chest wall pain and constitutional signs such as unexplained weight loss. The diagnosis may be suspected based on chest X-ray and CT scan findings, but must be confirmed either by examining serous effusion cytology or with a biopsy (removing a sample of the suspicious tissue). A thoracoscopy (inserting a tube with a camera into the chest) can be used to acquire biopsy material, and allows the introduction of substances such as talc to obliterate the pleural space (a procedure called pleurodesis), preventing more fluid from accumulating and pressing on the lung. Despite treatment with chemotherapy, radiation therapy or sometimes surgery, this form of cancer carries a poor prognosis. Research about screening tests for the early detection of mesothelioma is ongoing.

  1. I was not even aware this was a real problem until I started reading the articles here on TownSpeaks. Is there really that much of an issue with Mesothelioma, or is it just another scam blown out of proportion to make lawyers money?
