Figure 4. Sensitivity analysis for the likelihood of mastectomy at time of recurrence or new diagnosis on lifetime breast preservation for 60 year-old women at diagnosis.

Figure 4

The percentage change in lifetime breast preservation with radiation therapy (y-axis) varies with the likelihood of mastectomy at time of recurrence or new breast cancer (x-axis) in a previously non-irradiated breast. Radiation therapy is associated with a reduction in lifetime breast preservation unless the likelihood of mastectomy at time of recurrence or new breast cancer exceeds 66% (baseline stage-weighted average 32%).
