Summary
Brief summary
While ASA is not a cancer medication, research suggests that taking ASA reduces the
probability of getting many types of cancer because of its anti-inflammatory action.
Inflammation in the ovaries during ovulation is thought to contribute to the development of
ovarian cancer, and, because ASA is an anti-inflammatory medication, it may help to prevent
it.
