However, early AFP (≤20 years) and late AFP (≥30 years) increased the HRs of BCSM (HR = 1.49, 95% CI: 0.76–2.89 and HR = 1.50, 95% CI: 0.85–2.67, respectively) and OM (HR = 1.40, 95% CI: 0.94–2.09 and HR = 1.18, 95% CI: 0.83–1.68, respectively) (p <0.001) in postmenopausal breast cancer patients (Table 2). Here, AFP is linked to breast cancer.
