Hey Karen! I'm sorry to have missed this thread, since I don't visit here often, but I'm so glad Max is okay!
Jenna had one of these in the middle of her snout. Just popped up one day quick as you please. She had that excised under GA, turned out to be the same thing as Max...left the skin underneath all black.
Terrified me to see this thing as I too thought for sure it was some fast growing cancer. I'm over the moon for you, Max and Coop.
Much love and good health to all of you! ((((((((Huge hugs)))))))))) xxxx
