If you believe that you have been exposed to asbestos, it is important to seek medical attention and to document your exposure. You should keep a record of where and when you were exposed, as well as any symptoms that you have experienced. It is also important to tell your doctor about your exposure so that they can properly diagnose and treat any potential health problems. If you have been diagnosed with an asbestos-related disease, such as mesothelioma, your doctor will be able to provide evidence of your exposure.
