BOADICEA is a comprehensive model that can be used to calculate the future risks of developing breast or ovarian cancer using information on family history, lifestyle/hormonal risk factors, rare pathogenic variants in moderate and high risk breast/ovarian cancer susceptibility genes, common breast/ovarian cancer genetic susceptibility variants (Polygenic Risk Scores) and mammographic density. It can also be used to calculate the likelihood of carrying mutations in the moderate to high risk genes BRCA1, BRCA2, PALB2, ATM and CHEK2.
