CARE Model SAS Macro: Breast Cancer Risk Assessment for African American Women

The CARE Model is a SAS macro that allows researchers to estimate an African American woman's risk of developing invasive breast cancer. The CARE Model may be updated periodically as new data or research becomes available. 

Users can 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.

The NCI Breast Cancer Risk Assessment Tool has been updated to include the CARE Model information. Both the tool and SAS macro are designed for use by health professionals and researchers. 

If you are not a health professional, you are encouraged to discuss the results and your personal risk of breast cancer with your healthcare provider.
