Malignant mesothelioma is a fatal form of cancer often caused by exposure to airborne asbestos fibers. Due to a long latency period, symptoms of the disease typically take between 20 and 50 years to appear, often the disease is diagnosed in later stages and too late for any effective treatment. However, new treatment options continue to be researched.
