Absolute Risk curves used by the NSABP, based on the Gail Model

This table shows the Absolute Risk curves used by the NSABP model 2 calculator. On each graph, the x-axis is Summary Relative Risk, and the y-axis is the Percent Chance of developing breast cancer within Z years.  The columns in the table show Z = 5 years  and Z = 30 lifetime (to age 90).  The rows in the table show ages 20, 30, 40, 50, 60 and 70.

  Z = 5 years Z = lifetime (to age 90)
Age 20
Age 30 Breast cancer absolute risk
Age 40
Age 50
Age 60
Age 70

In each graph, the blue part of the curve reflects the output from the NCI's Breast Cancer Risk Assessment Tool,  and the gray part of the curve shows my estimate of the curve extended to higher values of Summary Relative Risk.
