Monkey

Cotton-top tamarin monkeys have a high rate of spontaneous colonĀ  cancer. They develop colon cancer in a very similar way to humans, so investigations of whether colon cancer is heritable - as it can be in humans - are now a focus of research. Other monkeys used in research include macaques and marmosets, mostly in brain research and in safety testing of new medicines. See our page onĀ Research Using Monkeys
