Researchers at OVC are establishing a population-based companion animal cancer registry. The registry project will begin as a pilot project focusing on all cancers within the dog and cat population in the city of Guelph (but will be expanded over time!). Cancer registries are an integral part of human cancer research. However, for companion animals, such registries do not exist in North America. Population-based cancer registries enable epidemiologists to study the occurrence of cancer in the population and to make statements when, where and why the occurrence of cancer is more or less likely in the population. This is a huge step forward and we could not do this without your continued support.
