Breast Cancer and the Brain: A Comprehensive Review of Neurological Complications

Breast cancer, one of the most prevalent malignancies globally, poses a substantial health burden with its diverse neurological complications. This comprehensive review examines the intricate landscape of breast cancer's neurological effects, encompassing brain metastases, non-metastatic complications, and their profound influence on the quality of life, prognosis, and survival of affected individuals. The mechanisms, clinical manifestations, and treatment modalities of brain metastasis and the critical role of interdisciplinary collaboration in their management are explored. Additionally, we address non-metastatic neurological complications, including paraneoplastic syndromes, treatment-related side effects, leptomeningeal carcinomatosis, and radiation-induced neurotoxicity, shedding light on the challenges they present and the importance of cognitive and emotional well-being. Prognostic factors and survival rates are discussed, emphasizing the complexity of variables impacting patient outcomes. Lastly, we underscore the vital role of collaborative care in addressing these multifaceted challenges, highlighting future research directions and the ongoing quest to enhance the quality of life for breast cancer patients.
