YAY!

Very late call around 10 pm from the vet's office to say that the results of the biospy on Busby's tissue sample came back and the lab confirmed that it really is just a nasty, long-standing infection. They said that multiple pathologists looked at the sample and were sure it was NOT cancerous.

I am very relieved. He still has a huge healing task to face, but it's so good to know it's not something (essentially) unbeatable.
