Chemotherapy is an essential component of breast cancer treatment, targeting rapidly dividing tumor cells to prevent growth and metastasis. In breast cancer, chemotherapy can be administered as neoadjuvant therapy, shrinking tumors before surgery, or as adjuvant therapy,
eliminating residual cancer cells post-surgery. Common drugs include anthracyclines, taxanes, cyclophosphamide, and platinum-based agents. Treatment is personalized based on tumor subtype, hormone receptor status, HER2 expression, and patient health. Side effects such as hair loss, nausea, and immunosuppression are managed through supportive care, including antiemetics, growth factors, and nutritional support. Combining chemotherapy with targeted therapies, such as trastuzumab for HER2-positive tumors, improves outcomes. Regular monitoring, imaging, and blood tests ensure efficacy and safety during therapy.
