Breast Cancer Risk Assessment Tool for Women With Benign Breast Disease (BBD)

The BBD/AH-BC model predicts the risk of developing future breast cancer for women after a breast biopsy showing benign findings, including atypical hyperplasia. The result of the model can be used to help providers and patients choose among options for surveillance and prevention of breast cancer.

Calculating Results

This calculator is intended for use by health care providers. The results should not be used alone to determine medical treatment. This tool is a statistical model and is not a substitute for an individual treatment plan developed by a health care provider with personal knowledge of a specific patient. Factors such as medical history and the health care provider’s experience, knowledge, and training must also be considered. Results should be discussed with patients when presenting prognoses or treatment recommendations.

To begin, please enter the patient's age at her benign biopsy

Please choose from the following categories.
