Maybe you already saw the story mentioned in our News Bytes: Cancer researchers have found evidence that women who use birth-control pills for a decade apparently double their risk of contracting cervical cancer.
Remember the artificial sweeteners called cyclamates? About 30 years ago, evidence emerged that cyclamates might have caused a slight increase in the rate of bladder cancer among laboratory rats who consumed prodigious quantities of the stuff. Notice that there was never a clear correlation; the evidence was inconclusive. And this was for lab rats; there was never any evidence of harm to humans.
Still, because there was a mere suspicion that cyclamates might be unhealthy, they were pulled off the market. You can't buy cyclamates in the US today. But you can buy birth-control pills.
We Americans take good care of our lab rats.
