Breast Cancer Screening: Ages 50 to 74

Breast cancer causes approximately 40,000 deaths in the United States each year. Early detection via mammography screening and subsequent treatment can reduce breast cancer mortality for women between the ages of 50 and 74.

Explore the percentage of women ages 50 to 74 who had a mammogram to screen for breast cancer in each state. Higher rates are better on this measure.

The purple dashed line represents the median, or middle, of all values reported.

This measure reports state performance on the percentage of women ages 50 to 74 who received a mammogram to screen for breast cancer during the measurement year or two years prior to the measurement year. 

States voluntarily report on Breast Cancer Screening (BCS-AD) as part of the Core Set of Adult Health Care Quality Measures. These data show performance rates for states that voluntarily reported the measure using Adult Core Set measure specifications.

The included populations for Adult Core Set measures can vary by state. For example, some states include populations in certain programs, such as beneficiaries covered by Medicaid, but exclude beneficiaries in other programs, such as those dually eligible for Medicare and Medicaid. In addition, states may include beneficiaries in some delivery systems, but exclude other delivery systems. For example, a state may include beneficiaries who are enrolled in managed care, but exclude beneficiaries who are covered on a fee-for-service (FFS) basis. This variation in populations can affect measure performance and comparisons between states.

Specifications for this measure changed substantially for Federal Fiscal Year (FFY) 2018. Rates for this measure cannot be trended from FFY 2017 to 2019.

The following states did not report data to the Centers for Medicare & Medicaid Services (CMS) for this measure: AK, AR, ID, ME, MT, ND, OR, and SD.

The Adult Core Set specifications include guidance for calculating this measure using the administrative method. Unless otherwise specified, the administrative data source is the state’s Medicaid Management Information System (MMIS) and/or data submitted by managed care plans, including behavioral health plans. This measure is also specified for calculation using electronic health records.

Unless otherwise specified:

  • States used Adult Core Set specifications, based on National Committee for Quality Assurance (NCQA) 2019 specifications.
  • Denominators are assumed to be the measure-eligible population for states using the administrative method. Some states reported exclusions from the denominator, as noted in the state-specific comments.
  • The measurement period for this measure was January 1, 2018 to December 31, 2018. AZ reported data for FFY 2018 and DE reported data for October 1, 2016 to December 31, 2018.  
  • Rates displayed reflect state reporting for Medicaid enrollees ages 50 to 64 (27 states) or ages 50 to 74 (16 states).
