My mother died of mesothelioma, asbestos cancer, is the last year. We have no idea where she was exosed so I try as much as possible about the places she has lived to learn. She lived in Carswell in the fifties. I wonder if someone knows something Carswell or its environs. If there are no factories around the area, or at what distance from the summit and the 5th Street (since mesothelioma was diagnosed 19 cases in this area). So you have all the information would be useful. Thank you very much!
