If you use any of four specific moisturizers (one of which is no longer sold, but the others are—gasp!—available at many fine retailers) and happen to be a mouse, your chance of skin cancer could be increased by as much as 95%.

Especially interesting:

The moisturizers did not cause cancer in the mice. That came from their early-life radiation exposure. But the creams did make skin cancers grow faster and more readily.

Who should worry now: Mice who use skin cream.

Why most of us shouldn’t freak out quite yet: No biological mechanism is known that could cause an increase in skin cancer rate (one of the criteria of causation).
