January 26, 2021 -- In the last 10 years, we have witnessed growing negativity regarding mammography screening. Numerous myths have sprung up about mammography, its effectiveness, and its potential complications, such as overdiagnosis. These unfortunate attitudes appear to be associated with the U.S. Preventive Services Task Force's (USPSTF) revision of mammography screening recommendations -- no longer recommending mammography screening for women ages 40 to 49. History of the USPSTF's decision in 2009 Dr. Matt Dyson. The USPSTF is a volunteer group of independent medical experts with preventive services expertise. Its primary task is making recommendations regarding screening tests, medications, and counseling services to prevent diseases. The USPSTF is funded by the U.S. Department of Health and Human Services; however, it makes its decisions independently.
