Tumor characteristics and surgical management related data were analyzed to compare two age groups. Statistical analyses included t-tests, chi-square tests, and Fisherâs exact tests.Results: Elderly patients presented with significantly larger tumors (3.91± 0.56 vs 2.81± 0.35 cm, p< 0.05), higher T4 disease prevalence (19.05% vs 3.37%, p< 0.05), and greater metastatic burden (7.90± 6.06 vs 3.54± 4.49 metastases, p< 0.05). SLNB was performed significantly more frequently in younger patients (90.9%) compared to elderly patients (71.4%, p < 0.05). Elderly patients underwent axillary dissection in 57.1% of cases compared to 33.3% in younger patients. Advanced tumors (T3+T4) were more prevalent in elderly patients with Luminal B HER2-positive (33.3% vs 0%, p< 0.0001) and Luminal B HER2-negative (37.5% vs 8.3%, p< 0.05) subtypes. Surgical management differed significantly between groups: mastectomy was performed more frequently in elderly patients (57.14% vs 31.31%, p< 0.05), whereas breast-conserving surgery was less common (42.9% vs 67.7%, p< 0.05).Conclusion: These findings demonstrate important differences in disease presentation and surgical management between age groups in Turkey, where breast cancer screening ends at age 69. The absence of screening detection in elderly patients, combined with their advanced disease presentation, highlights the need for further investigation with larger, multicenter cohorts to evaluate optimal screening strategies for women beyond age 69.Keywords: breast cancer, elderly patients, tumor subtypes, surgery, age-related disparities
