Selective Cox-2 inhibitors may have properties that help prevent breast cancer, a case control study here suggested.
When taken at standard doses for two years or more, the drugs were associated with a 71% reduction in breast cancer risk, reported Randall E. Harris, M.D., Ph.D., and colleagues at Ohio State in a study published online by BMC Cancer.
Regular use of non-selective Cox-2 inhibitors, such as aspirin and ibuprofen (Advil, Motrin), also reduced breast cancer risk but to a lesser degree, the researchers reported.
