Several advances in the field of cancer have been made through a comparative oncology approach. Recent national attention has highlighted the comparative oncology program:

Comparative oncologists study naturally occurring pet cancer to:

Understand environmental risks for human cancer.Companion animals may represent sentinels for environmental risk factors for cancer. Furthermore, these models may be helpful for the study of agents that may prevent cancers.

Examine genetic/familial determinants for cancer predispositions.The study of cancer genetics can be simplified by studies of cancer risk in breeds of dogs and within families of dogs. Cancer genes identified in dogs have been shown to be relevant in human familial cancers. This work will be enhanced with the progress of the canine genome project.

Improve our understanding of cancer biology and to add biological relevance to genomics data in experimental model systems.The availability of tumor samples from large populations of dogs contributes to their value to the study of cancer biology. The availability of molecular techniques and information from the canine genome project will enhance opportunities to study cancer biology that is informative for human disease in companion animals.

Evaluate novel therapeutic strategies.In addition to techniques such as chemotherapy, surgery, and radiation, approaches such as anti-angiogenesis, immunotoxins, and general immunotherapy are now being used to fight cancer. These novel treatments were tested first in animals.
