In contrast to BOADICEA, IBIS and BRCAPRO, which includes details about the ages of cancer diagnoses in the relatives as well as germline mutations in BRCA1/2, other breast cancer risk models like the commonly used Breast Cancer Risk Assessment Tool (BCRAT) generally consider family history based on the number of first-degree family relatives affected and/or ever/never family history. Here, BRCA1 is linked to breast cancer.
