Workers in Colorado who were exposed to asbestos materials on the job or in other locations may be at risk of being diagnosed with mesothelioma cancer, asbestos lung cancer, asbestosis, or other diseases caused by asbestos exposure.
Because the first symptoms of mesothelioma or other asbestos diseases may take decades after exposure for the first symptoms to appear, workers who were exposed as long as 50 years ago or more may only recently begun to have developed symptoms.
If you were exposed to asbestos – or are caring for a parent or loved one who was exposed – you may qualify to receive a free asbestos health exam to find out whether your symptoms are caused by an asbestos diseases.
To get your free health exam or to find out whether you qualify to file a claim, contact the lawyers at Hissey Mulderig & Friend by calling toll-free at 1-855-500-3734, or by filling out the free case evaluation form on the left side of this page.
