Methodology Notes

Data include women who have had a mammogram within the last 2 years. Healthy People 2020 uses the U.S. Preventative Services Task Force (USPSTF) guidelines to measure this objective, and the current USPSTF recommendation includes biennial mammography for women aged 50 to 74 years, with an additional recommendation that starting biennial mammography before age 50 should be an individual decision considering patient context, including a patient’s beliefs regarding possible benefits and harms.
