Daily Cancer News - CancerConsultants.com

More research is needed to understand the implications of this analysis. In the meantime the researchers caution that the results of this study should not change the colonoscopy screening recommendations. A 60% reduction in mortality is still an important benefit; in comparison, mammography reduces breast cancer mortality by only 25%.
