Breast cancer remains one of the leading causes of morbidity and mortality among women worldwide, with prognosis determined not only by early detection but also by tumor biology. Despite advances in molecular classification, current approaches are insufficient to fully predict disease progression, as recurrence and unfavorable outcomes occur even in clinically favorable groups. This highlights a critical knowledge gap in identifying reliable, accessible prognostic markers that reflect tumor heterogeneity and guide individualized treatment. This study analyzes systemic and local immunological and morphological predictors of breast cancer progression using existing clinical, histological, and molecular data. Particular attention is given to tumor grade, lymph node involvement, tumor size, receptor status, and emerging genetic factors such as microRNA expression. Findings demonstrate that tumor malignancy grade is a strong independent predictor of recurrence and survival, often exceeding the prognostic value of tumor size. Additionally, lymph node status and disease stage remain significant determinants of outcomes, while younger patient age is associated with more aggressive disease forms and lower survival rates. The results confirm that a multifactorial approach combining classical and emerging biomarkers improves prognostic accuracy. The study implies that integrating immunological and morphological indicators into clinical decision making could enhance risk stratification and optimize therapeutic strategies, potentially reducing unnecessary chemotherapy and improving patient quality of life.
