I don't believe Moose had anything on his lungs to begin with. The chest x-ray is part of the follow up. If the disease were to progress it might metastasize on the lungs. Since the lungs are clear 8 months later, it seems disease progression has stopped. There also are no other sarcomas growing elsewhere or regrowing at the treated site!
Incredibly encouraging!! Amazing stuff. One day outpatient treatment. Moose was out playing while other dogs would of still had days or weeks of beam radiation treatment ahead.
This is my understanding anyway.
The dog treated on humanitarian grounds has a growth in one lung indicating the cancer may have metastasized. It will be interesting to see the results of this dogs followup.
