Whether or not your dog’s breed is at high risk for mast cell tumors, you should take your pet to your veterinarian if you notice any suspicious skin mass.
The doctor will perform needle aspiration to evaluate the cells and determine what type of tumor it is. Once a mast cell tumor has been diagnosed, the veterinarian will surgically remove it.
Because mast cell tumors tend to be locally invasive, the doctor will have to make a wide excision to ensure all potentially malignant cells are removed from surrounding tissue. The surgically removed tumor will then be evaluated by a pathologist to determine its stage or “grade.”
