Since Bella has been doing so good after getting the steroid shot, we decided to call the vet. We told him about her progress and he seemed hopeful. He said it sounded like the steroid shot had shrunk the tumor a bit, and we could keep giving her the shots. There is a chance the tumor could get small enough to remove. However, there is also a chance she could become immune to the steroid.
We are just taking it one day at a time. Everyday that she is herself is a blessing. Thank you all for your prayers, keep it up. Hopefully we can get this tumor out!
