Wrongful death lawsuits can be filed over diseases caused by a person or companies negligent or intentional actions. These diseases are caused by a company's products or work environments. These companies would either have sold these products or put workers in harm's way while knowing the damage they could cause. Some common examples of diseases caused by these companies are mesothelioma and asbestos lung cancer (which are caused by asbestos exposure), and Leukemia and lymphoma (which can be caused by benzene exposure).
