An X-ray shows abnormalities like those Edie has in her lungs. They do not give a diagnosis. More tests need to be done to determine if this is pneumonia or cancer. They will look at the white blood cell count for infection and they can do cytology on the bronchial discharge to see if it’s infection or if cancer cells are present. If you want you can take Edie to a specialist to complete the additional tests needed to get a definitive diagnosis. Once there is a diagnosis then they can treat her appropriately. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Edie.
