Thanks a lot for the helpful posting. It is also my opinion that mesothelioma cancer has an particularly long latency period, which means that signs of the disease would possibly not emerge until 30 to 50 years after the initial exposure to mesothelioma.  Pleural mesothelioma, which can be the most common type and has effects on the area throughout the lungs, may cause shortness of breath, breasts pains, including a persistent coughing, which may cause coughing up bloodstream.
