The key to treating cancer may lie in cats, according to a recent study

The first detailed genetic study of cancer in domestic cats has revealed strong similarities to forms of cancer in humans, opening new possibilities for more effective treatments for both species.

Scientists analyzed the DNA of tumors from nearly 500 domestic cats and identified key genetic mutations linked to the development of cancer. Although cancer is a leading cause of illness and death in cats, until now little was known about how the disease develops in them.

"The genetics of cancer in cats has been largely uncharted territory until now. The more we understand about cancer in every species, the more we all benefit," said lead researcher Dr Louise Van der Wayden.

The international team, led by the Wellcome Sanger Institute in Cambridge, analyzed nearly 1,000 genes linked to 13 types of cancer in cats. The results showed that many of the genes that drive cancer in cats are the same as those in humans, suggesting that the two species share similar biological mechanisms that allow tumors to grow and spread.

According to scientists, domestic cats may be particularly helpful in understanding some forms of breast cancer, including “triple negative” breast cancer, an aggressive form that accounts for about 15% of cases in humans. Cats develop this subtype more often, providing researchers with more samples and opportunities to test new treatments.

Nearly a quarter of households in the UK have at least one cat, making this animal as widespread as the dog as a household companion. However, while studies on cancer in dogs are numerous, cats have largely remained outside the scientific spotlight.

Researchers point out that both cats and dogs can help identify environmental factors that influence the development of cancer, as they live in the same environments as humans and are exposed to the same risks.

“This helps us better understand why cancer develops in cats and humans, how the environment around us affects the risk of the disease and, potentially, find new ways of prevention and treatment,” said Prof. Geoffrey Wood from the Ontario Veterinary College in Canada.

The study, published in the journal Science, is considered an important step towards a broader cross-species approach in the fight against cancer.
