A. There could be several different diagnoses for the growth on your dog's leg including a cyst, an abscess or a mass. In order to determine what the growth is your veterinarian could perform a few different tests. 1) a fine need aspirate, which means your veterinarian uses a needle to insert into the mass and collect cells within the mass. Your veterinarian would then look under a microscope to determine what the cells are - a benign(harmless mass), cyst or malignant (cancerous mass). 2) a biopsy could be performed to remove either a portion of the mass or the entire mass and have this tissue sample evaluated by a pathologist.
