Does size matter in cancer?

Resumen

To be able to explain whether there is a relationship between size, lifespan and cancer risk we must first know what cancer is, how is thought thas was it's origin and finally see the relationship between these parameters in the Peto's paradox. That arose from Peto's studies in the 1970s. One possible answer to his paradox is that large animals (for example elephants) are less likely to develop cancer than short animals.
