Updated: Jan 12

Frequent aspirin use has been associated with reduced ovarian cancer risk, but no study has comprehensively assessed this effect. In a recent cohort study (a longitudinal study that includes a group of people who share a defining clinical characteristic) involving 8,326 patients, clinical researchers assessed study-specific associations between frequent aspirin use (≥ 6 days/week) and ovarian cancer risk. Additionally, ovarian cancer risk factors (endometriosis, obesity, family history of breast/ovarian cancer, nulliparity, oral contraceptive use, and tubal ligation) were also incorporated.

Frequent aspirin use is associated with a lower ovarian cancer risk.

Overall, frequent aspirin use was associated with a 13% reduction in ovarian cancer risk. This study, the largest to-date on aspirin use and ovarian cancer, provides evidence that frequent aspirin use is associated with a lower ovarian cancer risk, prompting further study of chemoprevention (the use of drugs to reduce the risk of cancer) strategies with frequent aspirin use that could potentially benefit patients who are at higher risk for developing ovarian cancer.
