Postoperative adjuvant therapy for breast cancer typically includes which combination?

• A. Radiation therapy and systemic therapy
• B. Antibiotics
• C. Observation only
• D. Vaccines

Answer: (A)

Postoperative adjuvant therapy aims to eradicate any remaining cancer cells after surgery, addressing both local and systemic disease. Radiation therapy to the breast/chest wall and regional lymph nodes reduces the risk of local recurrence, especially after breast-conserving surgery and in certain post-mastectomy cases. Systemic therapy targets micrometastatic disease throughout the body and can include chemotherapy, endocrine therapy for hormone receptor–positive tumors, and HER2-targeted therapy, all of which help lower distant recurrence and improve survival. Therefore, the typical adjuvant approach combines radiation therapy with systemic therapy. Antibiotics, vaccines, or observation alone do not address residual local disease or micrometastases.
