The Illinois public dataset is in ASCII format and contains sanitized individual records of cancer incidence among Illinois residents diagnosed from 1996 through 2000. Separate files are available for the state (IL9600.DAT), county (CNTY9600.DAT), and ZIP code areas (ZPCD9600.DAT). Confidentiality is maintained by aggregating data within individual records into categories, the number of which depend on the size of the geographic area.

Confidentiality of Public Use Cancer Files (PDF format). Health and Hazardous Substances Registry Newsletter, Illinois Department of Public Health,Spring 1999:1-2.

The ASCII data files are not incorporated into a software program and therefore require the use of other statistical or database software packages for data analysis (spreadsheet programs such as Excel, Lotus, or QPRO cannot be used as the number of records in each file is in excess of 260,000).

The README-I.TXT file provides record layouts, instructions, and general information for each data file.

The files include incidence data for invasive cancers only with the exception of cancer of the bladder. Carcinoma in situ of the breast is provided in a separate category. Non-melanoma skin cancers, cases reported with unknown or "other" sex, and cases with an unknown age are omitted.

Identification of cancer cases in ISCR is dependent upon reporting by hospitals as mandated by state law. In addition, ISCR has agreements with other central cancer registries in California, Florida, Indiana, Iowa, Kentucky, Michigan, Missouri, Wisconsin, and the Mayo Clinic in Minnesota to exchange cancer data. Completeness of out-of-state reporting depends upon the years of operation of these other central registries, the extent of their identification of out-of-state residents, and their standards of quality.

Please reference the source of data in any published document as follows: Illinois Department of Public Health, Illinois State Cancer Registry, public dataset, 1996-2000, January 2003.
