A new study has revealed a surprising genetic link between cancer in humans and cats. The research, considered the largest of its kind, analyzed tumors from approximately 500 pet cats across multiple countries and found significant overlap in genetic mutations between feline and human cancers.
Researchers at the University of Guelph in Canada extracted DNA from 13 different types of tumors found in the cats. They then mapped the sequence of 1,000 genes frequently mutated in human cancers. The findings, published recently, suggest that cats could play a role in developing new cancer treatments.
According to Al Arabiya, the study highlights the biological similarities between cats and humans, particularly regarding cancer development. Cats are increasingly diagnosed with cancer at rates similar to humans, and as their lifespans increase with improved healthcare and nutrition, the risk of developing cancer throughout their lives also rises.
“We find many types of cancer, or subtypes of it, that are common in cats and rare in humans,” the Youm7 report noted, specifically mentioning triple-negative breast cancer – a type lacking estrogen, progesterone, and HER2 growth factor receptors – as an example. This discovery could open doors to shared treatments that benefit both species.
Jafra News reported on March 22, 2026, that the research indicates that cancer in both cats and humans may originate from the same genetic mutations. This finding has significant implications for the development of novel therapeutic approaches. The shared genetic vulnerabilities could accelerate the discovery of new treatments applicable to both feline and human patients.
This research underscores the importance of comparative oncology – the study of naturally occurring cancers in animals to improve human health. The genetic similarities identified in this study offer a promising avenue for advancing cancer research and potentially leading to more effective treatments for both pets and people.
