Breast Cancer Risk Assessment SAS Macro (Version 4, Gail Model)

The Breast Cancer Risk Assessment Macro (commonly referred to as the Gail Model)  is a SAS macro that  projects absolute risk of invasive breast cancer in the batch mode, according to NCI’s Breast Cancer Risk Assessment Tool (BCRAT) algorithm for specific race/ethnic groups.

Users enter data on risk factors and projection interval ages for a group of women, and the macro will return the corresponding absolute risk projections. This program may be useful for researchers who need risk projections for an entire study population. Latest Update (March 2018): Includes the new Hispanic model
