Which statement best describes the treatment approach for post-menopausal breast cancer (stages I-IIIA)?

• A. Chemotherapy is always used first.
• B. Radiation therapy alone cures early disease.
• C. Dependent on hormone receptor status; surgery is primary curative treatment.
• D. Surgery is never used.

Answer: (C)

The main idea is that early-stage postmenopausal breast cancer is treated with a plan tailored to the tumor’s biology, with surgery providing the primary curative local treatment and systemic therapies added based on receptor status. In stages I–IIIA, removing the tumor through surgery (either breast-conserving surgery with lymph node assessment or mastectomy) is the central step aimed at curing the disease. After surgery, systemic therapy is chosen according to hormone receptor status: if the tumor is ER and/or PR positive, endocrine therapy is given (in postmenopausal patients, aromatase inhibitors are commonly used). If the tumor is hormone receptor–negative or carries other high-risk features, chemotherapy is more likely to be part of the plan. Radiation therapy plays a crucial role in reducing local recurrence, particularly after breast-conserving surgery or in certain mastectomy situations, but it is not used alone as a cure. Therefore, the statement that treatment depends on hormone receptor status and that surgery is the primary curative treatment best captures how this disease is managed.
