It has been massively consumed worldwide for many decades, without causing any statistically noticeable increase in cancer rates.

Considering the incredibly negative health impact of sugary drinks, artificial sweeteners probably prevented millions of deaths over the decades they have been used.

Like the other "scary" "it causes cancer" studies, they probably stuffed a rat with its body weight of aspartame and when it developed cancer they figured it's carcinogenic.

Completely disregarding that a can of artificially sweetened coke will have less than 1g of aspartame, which is 0.0002% of average human's bodyweight.
