Depending on the location of the lump, it could be Chico's lymph node that is the swelling. Those get swollen due to lymphoma, cancer, or infection. Any suspicious lump should be checked out by your vet. I recommend taking Chico into your vet to have that lump examined. Your vet can do a test called a fine needle aspirate to determine what that lump could be. To do this, your vet sticks a small needle into the lump 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.
