[Help] My dog has cancer!

Hi all, first-time poster here. Don't hate.This is devastating news. My cockapoo ( half poodle, half English Cocker spaniel), who is almost 7 years old, has been diagnosed with breast cancer. Her name is Amy. According to the vet, the tumor has been growing since February of this year. The surgery to remove the lump on her chest will cost around £500. I have a couple of questions. How long do you think she will live for? Will the surgery guarantee that the breast cancer won't come back? via /r/dogs http://ift.tt/2qJFslP
