Response

When your veterinarian or oncologist says they see a response they mean that the treatments you are using are working as hoped for. Sometimes they will say “the tumor was responsive,” which means the same thing. A response to treatment is a good thing. If they say your dog isn’t responding, that means it’s not working as hoped. Sometimes cancers respond to treatment at first and then stop responding, which prompts your veterinarian to look for another treatment to try.
