What is a Veterinary Oncologist?

A veterinary oncologist is a veterinarian with a minimum of 2 years of specialty training beyond veterinary school.  Most veterinary oncologists have completed a 1 year small animal internship followed by a 2 or 3 year residency training program in medical oncology.  In addition to residency training, certification as a Diplomate in the American College of Veterinary Internal Medicine, subspecialty of Oncology, requires satisfactory completion of a 2-part examination and publication of a research project in a peer-reviewed scientific journal.
