  1. Breast density was measured as dense area and categorised into quintile-decile groups. Predicted values are generated from regression modelling. We show the predicted programme sensitivity for 50- to 54-year-old women with no significant breast symptoms, not on hormone therapy and with no family history of breast cancer.
