Without seeing Jackie in person and doing tests on the lump, there is no way I can say if it's cancerous or benign. In an older dog, there is always a chance a lump could be cancerous. Any suspicious lumps 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 lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call today to make him an appointment. Best of luck.
