Figure 1.

Estimated hazards of breast cancer death from Poisson regression model. The blue curve represents the hazard of breast cancer death for women without recurrence. The dark red, bright red, dark orange, light orange, yellow, and black curves represent the hazard of breast cancer death for local recurrence diagnosed at different interval times (0.5, 1, 2, 5, 10, and 15 years). There were 5194 women who did not experience a locoregional recurrence (LR) (blue line), 34 women experienced LRs within 6 months, 85 women within 1 year, 108 women between 1 and 2 years, 174 women within 2–5 years, 103 women between 5 and 10 years, and finally, 62 women experienced LRs between 10 and 15 years following their primary diagnosis.
