New Publication on Mammography Use Shows Differences in States and Counties
A new CDC study, "Multilevel Regression for Small-Area Estimation of Mammography Use in the United States, 2014" was published online in the journal Cancer Epidemiology, Biomarkers & Prevention. The study looks at differences in mammography uptake among counties in the United States based on recommended breast cancer screening and the national objective for breast cancer screening (increase to 81.1% by 2020). According to updated recommendations in 2016, the U.S. Preventive Services Task Force (UPSTF) recommends breast cancer screening every 2 years for average-risk women aged 50-74 years. Study results show large differences in estimated proportions of women up-to-date with mammography and women who rarely or never had a mammogram. Twenty-one states were within 5% of the 2020 target of 81.1%. However, many counties were far below 80%. Counties with 15% or more of women who rarely or never had a mammogram, were located in more than half of the states, many in rural areas. These results suggest a need for planning and improving how resources are distributed on local levels to increase mammography uptake.
