Very High Risk Breast Cancer Screening

Very High Risk Breast Cancer Screening - which breast screening service (BSO) should a woman be referred to?

Breast screening for women at very high risk of breast cancer is co-ordinated through the NHS Very High Risk (VHR) Breast Screening Programme. 

The age at which screening starts depends on the underlying genotype and on the family history. Clinical genetics services do not have to wait until the age at which the woman’s screening protocol will start to refer her for breast screening; they can refer her straightaway and the breast screening service will invite the woman at the appropriate age. 

Referrals for VHR screening should be directed to the relevant Breast Screening Office.
