Input pedigree/family history data
- Can I include identical triplets or quads in risk calculations?
- Can the CanRisk Tool incorporate pathology information for a second (contralateral) breast cancer?
- How are BRCA1 and BRCA2 mutations defined?
- Can the CanRisk Tool estimate risks for Ashkenazi Jewish individuals?
- How should I estimate age at last follow up and/or year of birth when these data are missing?
- Does the CanRisk Tool take ipsilateral breast cancers into account?
- Why do BRCA mutation carrier probabilities sometimes increase abruptly when I increase an age at breast cancer diagnosis from 19 to 20 years in my input pedigree?
