Many studies have found that people who regularly use aspirin and other nonsteroidal antiinflammatory
drugs (NSAIDs), such as ibuprofen (Motrin®, Advil®) and naproxen (Aleve®),
have a lower risk of colorectal cancer and adenomatous polyps. Most of these studies looked
at people who took these medicines for reasons such as to treat arthritis or prevent heart
attacks. Other, stronger studies have provided evidence that aspirin can prevent the growth of
polyps in people who were previously treated for early stages of colorectal cancer or who
previously had polyps removed.
