Mesothelioma is a rare form of cancer that is always caused by previous exposure to asbestos. This cancer involves the mesothelium, cells, lungs, abdominal organs, and heart. The most common form of mesothelioma is pleural mesothelioma. 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, but it may also occur in the peritoneum or the pericardium. Exposure to airborne asbestos particles increases one's risk of developing malignant mesothelioma.
A brief description about mesothelioma
- Mesothelioma is usually caused by asbestos exposure. Asbestos is a fibrous mineral known to be carcinogenic. People who are exposed to asbestos fibers for just a short period of time (few weeks) or even to a small amount may be at risk. In particular, people working with asbestos and their family members or those who live with them are more likely to develop mesothelioma.
- The symptoms of mesothelioma include shortness of breath due to pleural effusion, chest wall pain, and weight loss. The diagnosis can be made with chest x-rays and CT scan, and it can be confirmed with the help of biopsy and microscopic examination.
- Unlike lung cancer, there is no association between mesothelioma and smoking.
