CATS CAN BE ‘A VITAL PARTNER IN THE FIGHT AGAINST CANCER’, NEW STUDY FINDS

Researchers discover that people share the same cancer-causing mutations as felines.

New research has revealed that the genetic mutations responsible for cancer are remarkably similar in cats and humans — positioning domestic cats as an important ally in advancing cancer research.

In a study published in Science, researchers identified key similarities between feline oncogenes (mutated genes that can drive cancer growth) and the human oncogenome. One of the most frequently mutated genes, TP53, appeared in 33% of feline cancers and 34% of human tumours, highlighting a striking overlap between the two species.

Dr. Latasha Ludwig, co-author of the study and assistant clinical professor at Cornell University’s College of Veterinary Medicine, noted that the findings confirm cats are more than beloved companions — they are valuable partners in the fight against cancer.

Because cats share our homes and environments, they are exposed to many of the same risk factors as humans and develop many of the same diseases. This strengthens the case for comparative cancer studies between the two species.

The cancers most closely aligned between cats and humans were breast cancer and squamous cell carcinoma. Researchers say the findings support the “One Health” approach — the idea that human and animal health are deeply interconnected.

Senior author Dr. Louise Van Der Weyden added that the next step is advancing precision feline oncology, improving diagnostic and treatment options for cats, and potentially informing cancer care for humans in the future.
