What evidence at a minimum is required for an asbestos claim?

Bodily harm or physical impairment must be shown by the plaintiff.  This usually means furnishing proof that asbestos was the leading contributor (rather than other factors such as long-term smoking) to their asbestosis, and that asbestos was the direct cause of their asbestosis.  Typically, the following types of proof of injury concerning asbestosis will be sufficient: 1) A chest x-ray corroborating the presence of asbestosis that satisfies or exceeds the prescribed range and 2) the opinion of a  board-certified pathologist that the patient's respiratory impairment has attained a certain level and that he or she has a certain scarring pattern.
