One of the most devastating diagnoses for most individuals is that of mesothelioma asbestos lung cancer. It is especially devastating since it may be impossible for the individual to be able to track down and back in time to the exact location of exposure throughout their career. Typically mesothelioma is caused by direct, prolonged and sustained exposure to above average levels of asbestos in the environment. This is often the workplace, especially for those that worked in construction, refining, shipbuilding or demolition in the earlier parts of the 20th century. Even today asbestos is still used, however additional safety precautions and workplace protection is in place. The biggest tragedy in this diagnosis is that there is not a cure for mesothelioma asbestos lung cancer and usually by the time it is diagnosed it has become malignant and spread to other organs in the body. Anyone that believes they have been exposed to asbestos in airborne form in their workplace or home environment needs to talk to a doctor, especially if they have any chronic health issues, are smokers or have chronic or very frequent respiratory problems or coughing.
