National Aggregate

Five-Year Summary: January 2016 to December 2020

Tables and graphs report on cancer screening and diagnostic services provided through the program in a recent 5-year period. The data represent clinical services funded directly through the NBCCEDP as reported in the October 2021 submission of the NBCCEDP Minimum Data Elements (MDE).

National aggregate data are typically used to report results from the program and as a standard to compare results of grantee programs. Comparing data across grantee programs is not advised due to extensive variation across programs. For information on interpreting the data, refer to Screening Program Data. For information on the program, refer to About the Program.

Data for the following are suppressed for programs with fewer than 200 screens, cell sizes less than 16, and rates and percentages that do not meet a test of relative standard error less than 30%, a measure of the estimate’s reliability. Differences are due to rounding.

Service Totals by Year

This bar graph illustrates the number of women who received NBCCEDP-funded services by calendar year from January 2016 to December 2020.

Program Overview

1: Abnormal HPV test results include: all positive high-risk HPV test results.

2: Abnormal Pap test results include: low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), atypical squamous cells of undetermined significance – cannot exclude HSIL (ASC-H), atypical glandular cells (AGC), and squamous cell cancer.

3: Adjusted to the age distribution of NBCCEDP participants having Pap tests performed in calendar year 2000.

4: Includes LSIL, HSIL, cervical intraepithelial neoplasia (CIN)1, CIN2, CIN3, carcinoma in situ (CIS), and invasive cervical cancer.

5: Includes HSIL, CIN2, CIN3, CIS, and invasive cervical cancer.

Table includes HPV and Pap tests provided to women with services funded through the NBCCEDP. An additional 655 women, not included above, were diagnosed with LSIL, HSIL, CIN1, CIN2, CIN3, CIS, or invasive cervical cancer through the NBCCEDP following a Pap test with services funded through another source.

1: Abnormals include mammogram results of: suspicious abnormality, highly suggestive of malignancy, and assessment incomplete (further imaging studies or film comparisons required).

2: Adjusted to the age distribution of NBCCEDP participants 40 years of age and older having mammograms performed in calendar year 2000.

3: Breast cancers include invasive breast cancer, ductal carcinoma in situ (DCIS), and other in situ excluding lobular carcinoma in situ (LCIS).

Table includes mammograms provided to women age 40 and older with services funded through the NBCCEDP. An additional 70 women, not included above, were diagnosed with CIS (other), DCIS, or invasive breast cancer through the NBCCEDP following a mammogram with services funded through another source.
