Scientists studied cat tumors to find genetic changes that could help treat human cancers. They found similar patterns in both species.

Cancer is a major problem for cats, just like it is for humans. Scientists wanted to learn more about the genetics of cancer in cats. They analyzed nearly 500 tumor samples from pet cats across five countries. The team included experts from the Wellcome Sanger Institute, the Ontario Veterinary College, and the University of Bern.

The study found that many genetic changes driving cancer in cats are similar to those seen in human cancers. This means that new treatments for cat cancer could also help humans. One example is mammary cancer in cats, which has a similar pattern to breast cancer in humans.

Cats and their owners often share the same living environment, so they can be exposed to similar cancer risk factors. The study used DNA sequencing on tissue samples originally collected for veterinary diagnostics. This allowed them to identify key genetic alterations that drive cancer in cats.

The team screened around 1,000 genes linked to human cancer and compared tumor and healthy tissue samples across 13 different types of feline cancer. They found that certain chemotherapy drugs were more effective in tumor samples with specific mutations.

Why It Matters

This study shows how studying animal cancers can help us understand and treat human cancers. As India's pet cat population grows, this research could lead to new treatments for feline mammary cancer and potentially even human breast cancer.
