ABSTRACT:
Breast cancer is the most frequently diagnosed malignancy among women worldwide and remains a leading cause of cancer-related mortality¹. Recent global estimates indicate a rising incidence across both developed and developing nations, with disparities in survival linked to access to screening and treatment². Breast cancer is a biologically heterogeneous disease influenced by genetic susceptibility, hormonal exposure, environmental factors, and lifestyle behaviors³. Molecular characterization based on hormone receptors and HER2 expression has transformed clinical decision-making and enabled precision-based therapeutic approaches4. Standard management involves a multidisciplinary strategy incorporating surgery, radiotherapy, chemotherapy, endocrine therapy, targeted agents, and immunotherapy5?8. Innovations such as antibody–drug conjugates, CDK4/6 inhibitors, PARP inhibitors, immune checkpoint inhibitors, and genomic profiling have substantially improved patient outcomes6??. Despite these advances, challenges including metastatic progression, therapeutic resistance, long-term toxicity, and healthcare inequities persist¹°. This comprehensive review discusses epidemiology, risk factors, molecular mechanisms, classification, clinical presentation, screening, diagnosis, staging, therapeutic strategies, complications, prevention, and emerging research directions in breast cancer management.
