US Preventive Services Task Force and breast cancer screening.

The US Preventive Services Task Force (USPSTF) was established more than 2 decades ago as an independent panel of experts in primary care and preventive care with the mandate to conduct rigorous, unbiased assessments of the scientific evidence for the effectiveness of clinical preventive services. The task force uses state-of-the-art methods and explicit criteria for assessing the available evidence and issues recommendations for prevention interventions along with the strength of evidence supporting those recommendations, thereby enabling research on prevention to be translated into clinical practice.
