Why mice don't get cancer of the retina

Humans are more susceptible to developing the eye cancer retinoblastoma than mice because, unlike humans, mice can compensate for the loss of activity of a gene critical to normal retinal development , according to results of a study by investigators at St. Jude Children's Research Hospital. The stu...
