Non-nutritive sweeteners and human bladder cancer: preliminary findings

The non-nutritive sweeteners, saccharin and cyclamate, were not associated with the risk of human bladder cancer in a controlled investigation. The prior intake of such sweeteners in any and all forms was not greater or more prolonged among 209 recently diagnosed bladder cancer patients than among 209 otherwise similar patients without bladder disease. These findings were unaffected by case-control differences in diabetic histories or smoking practices.
