So, I dropped her off to the vet this morning for her biopsy. The vet was able to remove a good portion of the visible mass - which has decreased her massive hump and decreased some of the pressure on her right eye. The bad portion is that the vet said she thinks it is cancer. I will not know officially for 3-5 business days when the results of the biopsy state what it is and if it is cancer, what type it is. I just gave sydney a bowl of her favorite food and she seems to be in good spirits. These next few days, I am just going to focus on giving her the best love I can, and then take it from there. Thanks again for everyone being so supportive and everyone giving me some really helpful information. It is greatly appreciated.
