I've worked in human medicine for over 30 years and there are small differences but enough family how often if ever can keep originate in the liver or was that metastasis?

Accepted Answer

Mesothelioma in dogs is strongly correlated to asbestos like in humans; but other chemicals have been found to cause mesothelioma in a laboratory setting in rodents. Mesothelioma originates from the mesothelial cells which line the body cavities and internal organs and helps to provide a non-adhesive and protective surface so that organs slide freely against each other and don’t form adhesions. If you are looking for more concrete answers, I would recommend having Loki examined by a Veterinary Pathologist for more information. Regards Dr Callum Turner DVM
