The Claim

In a case-cohort analysis of 1,234 participants from the Moli-sani Study with 13.2 years of follow-up, the presence of sucralose in urine was associated with a 4.23-fold higher risk of premenopausal breast cancer in middle-aged women, although this finding is based on a small number of cases and should be interpreted cautiously.

In plain English

If sucralose shows up in a woman's pee, she might be more likely to get breast cancer before menopause — especially if she's in her middle years — but the data isn't super strong yet.

  1. Study: Urinary artificial sweeteners and breast cancer risk in women from the Moli-sani Study

    The study found that women who had sucralose in their urine were more likely to develop breast cancer before menopause, which matches the claim. The researchers also said this result should be taken with caution because there weren’t many cases.
