Abstract
We examined effects of ibuprofen on the growth and development of DMBA-induced mammary cancers in mature female Sprague-Dawley rats. Ibuprofen was added to the standard diet at approximately 1,000 mg/kg rodent chow, resulting in an average daily dose of 25 mg per day per 0.25 kg rat. After five weeks of ibuprofen treatment, there was a 37% reduction in tumor volume compared to a 260% increase in the volume of tumors in untreated rats (p<0.001). These results suggest that ibuprofen may have potential in the chemoprevention and treatment of breast cancer.
