alt Hacker NewsDon't know about mice, but rats more or less have a 50% tumor/cancer chance if they really do get to live 1+ years. I think for some lines it goes up to 90%+.

Every rat (4 now) I've owned except one has died of cancer. Or at least, they died with cancer, I'm not a veterinarian. The one that didn't got the flu or something at 6 months and died of some respiratory issue.
