Researchers have identified a unique leopard gecko that naturally develops aggressive tumors, making it a promising new model for cancer research. Genetic analysis revealed that its tumors share many of the same mutations and biological pathways found in human cancers, providing scientists with a rare opportunity to study cancer as it develops naturally. Unlike laboratory animals that require tumors to be artificially induced, these geckos develop cancer at a young age, with tumors that often spread throughout the body. This could help researchers better understand how cancer starts, progresses, and metastasizes. The findings suggest that studying naturally cancer-prone species may complement existing research models and lead to new insights into cancer prevention, diagnosis, and treatment in humans.
