The Claim

Genetically predicted aspartame intake is associated with a 110% increased risk of ovarian cancer (OR = 2.10, 95% CI: 1.06–4.18) in individuals of European ancestry.

People with genetic markers suggesting higher aspartame consumption have a higher rate of ovarian cancer compared to those without those markers.

See the scientific wording

Genetically predicted aspartame intake is associated with a 110% increased risk of ovarian cancer (OR = 2.10, 95% CI: 1.06–4.18) in individuals of European ancestry, suggesting a potential link between long-term artificial sweetener consumption and ovarian cancer development.

Why this might work

Aspartame attaches to three specific proteins in ovarian cells, making them overactive. One protein forces cells to divide too quickly, another pushes cells to start dividing before they are ready, and the third helps damaged cells avoid dying. Together, this causes ovarian cells to multiply uncontrollably and survive when they should die, leading to tumor growth.

    People who have genes that make them more likely to consume aspartame also have a higher chance of getting ovarian cancer, and lab tests show aspartame might directly fuel cancer cell growth by affecting specific genes.
