National Aggregate

Five-Year Summary: January 2011 to December 2015

Tables and graphs report on cancer screening 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 2016 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.
