The choice of animal model depends on the type of cancer being studied and the research objectives. Mice are the most commonly used animals due to their genetic similarity to humans and the availability of genetically modified strains that can mimic human cancer. Other animals, such as zebrafish and rats, are also used for specific types of cancer studies. Researchers select models that best replicate human cancer biology and progression, ensuring that the findings are relevant and translatable to human clinical trials.
