I wouldn't worry about. Personally, I drink Diet Coke (nectar of the gods). I don't think there has ever been a study on humans with a link to any cancer or specific issues. They have shown in rodents a link to cancer. However, the amount relative to body weight that the rodents were given was extreme. Anything in the extreme amounts in the studies is bound to cause problems. As they say, too much of anything is a bad thing. I bet they could link cancer to any chemical, mineral, supplement, etc in such quantities. Here are 2 studies: http://cebp.aacrjournals.org/content/15/9/1654.full?ijkey=ac6c97b1ce31ada1c45888d3101fd0b9d5901fe7 http://cebp.aacrjournals.org/content/15/9/1654.full?ijkey=ac... http://annonc.oxfordjournals.org/content/18/1/40.full http://annonc.oxfordjournals.org/content/18/1/40.full My honest humble opinion is don't worry about. Drink your sweetened coffee and Diet Coke if you enjoy it. I believe I read some where that sweeteners are the most studied elements in the world and if there was a problem, a serious problem, I think it would have been known by now.
