Menstrual pain and epithelial ovarian cancer risk
This case-control study found that women reporting moderate or severe menstrual pain in their twenties and thirties had an increased risk of epithelial ovarian cancer.

This case–control study investigated whether menstrual pain severity during women’s twenties and thirties (when not using oral contraceptives or breastfeeding) is associated with risk of epithelial ovarian cancer, using 2,028 cases and 2,091 age- and study center-matched controls. Participants self-reported menstrual pain, and the authors used unconditional logistic regression overall and polytomous logistic regression to assess differences by tumor histologic subtype. They found higher ovarian cancer risk for moderate pain (OR 1.22, 95% CI 1.05–1.42) and severe pain (OR 1.34, 95% CI 1.09–1.65) versus no or mild pain, with stronger associations for severe pain with endometrioid (OR 1.64) and clear cell tumors (OR 1.91). The paper notes a limitation that the analysis relies on self-reported menstrual pain, which is common in the population and therefore warrants further studies. Relevance to endometriosis: the study frames its inflammatory dysmenorrhea context by citing relationships among dysmenorrhea, inflammatory eicosanoids, and endometriosis-related mechanisms, though it does not directly measure endometriosis or adenomyosis in participants.
