Cancer in Rats

[fraserjim]

Is it true that research is Known to cause cancer in rats

[bluedolphin]

The answer is YES. As is the scientific fact that the wind is caused by the trees flapping their branches.

[DavidUK]

Some animals are bred specifically to get cancer so that researchers can carry out painful experiments on them, kill them and then dissect them.

[Squirrel]

I would guess that they modify some rats to give them much less hair, then subject the bare skin to ultraviolet radiation (or whatever else causes skin cancer) and observe the effects. I consider this unnecessarily cruel - why can't they just experiment on bacteria or ants?

[Taurwen]

Why are ants better then rats? Because they arn't as cute? Hardly a reason.

i dont quite understand the wording of this question. if you mean did research and experimentation cause cancer to be a problem with rats then yes. because most rats are descended from the lab rats, pet rats are prone to cancer.
