Scientists studied cancer in domestic cats to understand human cancer better. They found similar genetic changes and discovered new treatment possibilities.

Cancer is a major problem for both humans and house cats. Researchers wanted to learn more about the genetics of cancer in cats to help us understand and treat it better in humans too. A team of scientists analyzed tumor samples from nearly 500 domestic cats collected across five countries. They found many of the same genetic mutations that drive cancer in humans and dogs. This is important because some cancer risks might be linked to environmental factors that both humans and cats are exposed to.

The study discovered that certain chemotherapy drugs worked better in cat mammary tumors with a specific gene mutation. This could lead to new treatment options for breast cancer in both animals and humans. The research also showed similarities between feline and human cancers affecting the blood, bones, lungs, skin, gastrointestinal tract, and central nervous system.

The study's findings can help us understand why cancer develops in cats and humans, how our environment affects cancer risk, and possibly find new ways to prevent and treat it. The international project brought together researchers from several institutions to sequence DNA from tissue samples collected for diagnostic purposes. This collaborative approach is known as the One Medicine strategy, which encourages the exchange of knowledge between veterinary and medical researchers to improve health outcomes across species.

Why It Matters

This study shows that by studying cancer in house cats, we can gain insights into human cancer too. As pets are an integral part of many Indian families, understanding how cancer affects them can lead to better treatments for both humans and animals.
