NB halls.md Disclaimer: "
This calculator uses the Gail model (named after Dr. Mitchell H. Gail), and is a slightly less-than-perfect emulation of the NCI's Breast Cancer Risk Assessment Tool, but with the benefit of additional risk modifier questions added. Although this calculator is based on published risk statistics and methods gathered from peer-reviewed journals, this web page's specific methods and results have not been peer-reviewed. So, you should not use the results for medical decisions. The results are estimates."
Dr. Halls also makes the following important comment:
"Because this calculator includes extra risk modifiers and correction factors that were not originally part of [Gail] model 1 or [NSABP] model 2, it is not possible to demonstrate that the results are accurate from published population-based studies. Therefore, please consider these results to be an estimate."
