Scientists say house cats could help unlock new cancer treatments for humans
Scientists have discovered genetic links between cancers in house cats and humans, which could lead to new cancer treatments for both species. The study analyzed nearly 500 cat tumors and found shared cancer-driving genes, particularly linked to aggressive breast cancers. This research may enhance understanding of cancer development and treatment options for both pets and people.
- ▪Researchers analyzed tumor samples from nearly 500 domestic cats across five countries.
- ▪The study revealed that many genetic mutations in cat cancers are similar to those found in human and dog cancers.
- ▪Mutations in the FBXW7 gene, linked to aggressive mammary cancers, were found in over half of the cat tumors studied.

Science News from research organizations Scientists say house cats could help unlock new cancer treatments for humans Scientists have uncovered surprising genetic links between cat and human cancers — and the discovery could reshape cancer treatment for pets and people alike. Date: May 24, 2026 Source: University of Guelph Summary: Scientists have cracked open the “black box” of feline cancer in a landmark study that genetically analyzed nearly 500 cat tumors from around the world. The research uncovered striking similarities between cancers in cats, dogs, and humans — including shared cancer-driving genes tied to aggressive breast cancers.
