Oh no! I hope its not cancer!

My guinea pig Taffy has a tumor on his side. When we took him to the vet they said it wasn't cancer, but they could do surgery to remove it. Since he is about 6 years old, we didn't think it was a great idea. (They said there was a risk of him not waking up becuase he was so old)
