Registries for human cancers have existed since the 1940s, helping researchers and clinicians understand how common different types of cancer are, risk factors, and the best way to treat different types of tumors.
Yet there is no such registry for our closest non-human companions; our pet dogs and cats who share our homes (and often the food from our tables), and who also suffer from cancer. Data about cancer in pets could improve cancer outcomes for our closest companions, and for humans as well.
