How are metal levels in whales and bladder cancer related?

I wanted to give a shout out to another experiment.com campaign run by our friend John Wise, whose group is studying metal pollutant levels in whales.

Experiment.com will give $2,000 to the marine mammal project with the most donors (even twenty cents counts!) by midnight west coast time tonight.

You might ask, does this have anything to do with bladder cancer?

Surprisingly, they're not entirely unrelated topics, as heavy metal exposure is a risk factor for the development of bladder cancer, and a major source of this risk comes from seafood and more generally, anything grown with polluted water. In fact, John's group also studies the relationship between metal exposure and bladder cancer pathogenesis.

So check it out!
