My dad was exposed to asbestos while at work which lead to him contracting the deadly disease, eventually leading to his untimely death. The symptoms of Mesothelioma were non-specific and it took more than 30 years to appear from the time he was exposed to asbestos at his workplace. The symptoms included shortness of breath and severe pain in his chest due to accumulation of fluid around his lungs. It also led to him losing weight.
