Thanks for the helpful aclirte. It is also my opinion that mesothelioma cancer has an incredibly long latency period, which means that indication of the disease may well not emerge right until 30 to 50 years after the first exposure to asbestos fiber.  Pleural mesothelioma, which can be the most common form and has an effect on the area around the lungs, might result in shortness of breath, torso pains, including a persistent cough, which may result in coughing up blood.
