Cleo was diagnosed with a pancreatic tumor today. It had been 7 months since she was diagnosed with diabetes and I just had a hunch that she needed to be seen. She wasn't isolating and her appetite was fine. I don't know why I thought she needed a check up. The vet felt a mass in Cleo's abdomen and ultrasound confirmed that it was a tumor on her pancreas. The vet doesn't recommend surgery or steroids. She said that Cleo is not in pain and that, as long as that is the case and she doesn't seem ill, I can wait for her to tell me when it's time to let her go. The vet thinks the tumor is the cause of Cleo's diabetes. Her insulin dose has gradually increased from 1 to 1.6 units since her diagnosis. I expect that to continue as the tumor grows. I was wondering if anyone else has experienced something like this. The vet was supportive but didn't have a lot of information about what to expect.
