Mesothelioma is a form of cancer that affects the mesothelial cells lining the lung, chest cavity, abdominal cavity or heart cavity. These mesothelial cells also cover the outer surface of most internal organs forming a tissue called mesothelium that helps protect the organs. Although tumors of the mesothelium can be benign (noncancerous), most cases are malignant (cancerous). Virtually all cases of malignant mesothelioma are attributable to asbestos exposure and are both difficult to diagnose and poorly responsive to therapy. As this form of cancer can occur 20 to 60 years after the initial exposure, it is important to recognize the most common symptoms which include:
- Anemia
- Back pain
- Chest pain
- Cough
- Enlarged abdomen
- Fever
- Hoarseness
- Recurrent build-up of fluid in the lungs
- Shortness of breath
- Weight loss
