With how quickly the bump appeared on Ellie, I recommend having your veterinarian take an aspirate of it. An aspirate consists of your veterinarian placing a needle in the growth to try to collect cells. They can then evaluate it under a microscope or send it to a pathologist to evaluate. This may or may not get us a complete answer. The bump could be a benign (non-cancerous) growth but it also could be something to be concerned about. The best way to determine if this is something at all to be concerned about is to remove the growth under anesthesia, send the growth to a pathologist and have a pathologist examine the tissue.
