Veterinary oncology is a subspecialty of veterinary medicine that deals with cancer diagnosis and treatment in animals. Cancer is a major cause of death in pet animals. In one study, 45% of the dogs that reached 10 years of age or older died of cancer.[1]
Skin tumors are the most frequently diagnosed type of tumor in domestic animals for two reasons: 1. constant exposure of animal skin to the sun and external environment, 2. skin tumors are easy to see because they are on the outside of the animal.[2]
