Yep, and saccharin (my sweet poison of choice) has been linked to bladder cancer.
The REALLY bad news? Pretty much, if it's sweet, it's deadly - no way around that.
That said, according to what I've read (and I've read a shit ton on this, because I HAVE a sweet tooth), the least deadly sweets are (in descending order or preference):
Stevia
Xylitol
Dextrose
...and bringing up the rear, with just a hint of bladder cancer, Saccharin.
If I could get Dextrose or Xylitol in the supermarket, I'd probably be getting those more often. Stevia isn't terribly sweet, and it's a bit fucking slimy.
This is a no-win if you like anything sweet. If it's sweet, it's probably poison.
