Figure 1. Cumulative Breast Cancer Incidence in Relatives of Probands.
The graphs show the estimated cumulative risks of breast cancer in first degree female relatives of different categories of proband. The benchmark is the cumulative risk of breast cancer reported by the SEER registries (see text). Pink - SEER 1990-1994; Blue - Cumulative risks in relatives of non-carrier UBC probands; Orange - Cumulative risks in relatives of non-carrier CBC probands; Green - Cumulative risks in relatives of BRCA1/2 carrier UBC probands; Yellow - Cumulative risks in relatives of BRCA1/2 carrier CBC probands.
