This growth on Blu could be a cyst, a benign tumor, or a malignant tumor. Any suspicious growths should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the growth to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Blu seen by a vet tomorrow to have the growth examined and diagnosed so it can be treated as needed.
