Researchers unveil 1 million-record dog and cat tumor database
Researchers at the University of Liverpool and the University of Las Palmas de Gran Canaria say they’ve built the world’s largest open-source database of canine and feline tumors, with more than 1 million records pulled together to support cancer surveillance and research in companion animals. The project expands on earlier SAVSNET work that published a UK pathology-based registry of about 109,895 tumors in 2021, and the new announcement positions the enlarged database as a way to detect patterns in rare cancers, breed-associated risk, and other signals that smaller, fragmented datasets can miss. Large hospital-based datasets underscore that need: a 20-year California study covering 150,063 dogs and cats found age was the strongest predictor of several major cancers, with additional sex- and neuter-related effects that varied by tumor type, and concluded that a dedicated companion-animal cancer registry is needed for a fuller epidemiologic picture.

Why it matters: For veterinary professionals, the significance is less about the headline number than the infrastructure behind it. Veterinary cancer surveillance has long been limited by inconsistent coding, fragmented registries, and uneven geographic coverage, which makes it hard to compare findings across studies or build reliable risk estimates. A larger, open-source dataset could strengthen epidemiology, support earlier hypothesis generation around breed, age, sex, and tumor-type associations, and help comparative oncology efforts that link pet and human cancer data under a One Health framework. That comparative angle is becoming more concrete: recent large-scale feline genomics work in Science profiled 493 cat tumors across 13 cancer types and found recurrent mutations in genes such as TP53, FBXW7, and PIK3CA, including strong parallels between feline mammary carcinoma and human breast cancer.

What to watch: The next question is whether the database is formally published with methods, access details, and standardization rules that let outside researchers validate and build on it at scale. It will also matter whether the resource can connect population-level surveillance with newer precision-oncology work, such as genomic profiling and noninvasive blood-based response markers being explored in canine lymphoma.
