Palpable vs non-palpable breast cancers in screened populations: Clinicopathological features and prognostic implications

Figure 1 Kaplan-Meier estimated 10-year overall survival and breast cancer-specific survival stratified by palpable vs non-palpable lesion status. A: Overall survival; B: Breast cancer-specific survival.

Figure 2  Biennial incidence of palpable and non-palpable tumors, and temporal trend in the proportion of palpable tumors among all diagnosed cases.

Figure 3 Correlation between tumor size and Ki-67. Spearman’s correlation analysis revealed a weak but statistically significant positive association between histological diameter and Ki-67 index (P = 0.282, P < 0.001), suggesting that larger tumor size may correlate with higher proliferative activity.
