Don'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.

Rats have such bad PR.

They make fun affectionate pets if you can stomach the idea that they will die on you.

How did you diagnose the cancer?

		There's nothing subtle about cancer in rats, especially the females. They're terribly prone to breast cancer and female rat has a lot of breasts. You'll see golf ball sized things in no time unless you're willing to pay for removals. Very common and any vet will spot it. When they get a 'lump' it grows real quick. They make lovely, interactive pets, and very intelligent but they will break your heart and die too soon.
