HI, I am new to the forum and wanted to introduce Doc. He's my wonderful 12yo Border Collie. We have just been diagnosed with a functioning pituitary adenoma (brain tumor). He was diagnosed by an MRI. As you can imagine, I'm still spinning. The neurologist said it was functioning so that he has Cushing's. We are going to pursue radiation therapy in order to reduce or kill the tumor. The radiation they recommend is 5 doses in a week's time. I am calling tomorrow to schedule this. Doc's symptoms started in July and we had xrays done and showed arthritis in the spine. We just thought we had an old dog. But, he started to do other things like dropping his neck, getting very quiet, drinking a lot and peeing a lot, dragging his nails on walks, and general confusion. They thought he had degenerative myelopathy, but last week confirmed that it is a tumor. Right now, they want to do the radiation then focus on the after support when they get an idea if he needs steroids or not. I have him on Chinese herbs, he is getting acupuncture, and massage. I am so happy I found this forum and so glad there is a community of people who don't think I'm crazy for what I do for my boy. My question is, does anyone have any experience with the radiation therapy and what to expect afterwards? Thanks and I look forward to being a part of this community.
