Mesothelioma is a form of cancer that is almost always caused by previous exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body's internal organs.
Its most common site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the pericardium (a sac that surrounds the heart) or tunica vaginalis.
Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, or they have been exposed to asbestos dust and fiber in other ways.
The Mesothelioma Center within the Herbert Irving Comprehensive Cancer Center at NewYork-Presbyterian Hospital and Columbia University Medical Center is now recruiting patients for a clinical research study of a new targeted radiation and chemotherapy protocol for pleural mesothelioma, a cancer of the lung's lining that is almost always caused by previous exposure to asbestos.
A major study in Nature Nanotechnology suggests some forms of carbon nanotubes -- a poster child for the nanotechnology revolution -- could be as harmful as asbestos if inhaled in sufficient quantities.
