Which imaging modalities are commonly used to detect metastatic disease in breast cancer?

• A. Ultrasound and Mammography
• B. CT Imaging, Bone Scans, or PET-CT
• C. MRI
• D. Sputum Cytology

Answer: (B)

Detecting metastatic spread in breast cancer relies on systemic imaging that surveys distant sites, not just the breast itself. CT imaging provides detailed cross-sectional views of the chest, abdomen, and pelvis to spot organ metastases. Bone scans are especially useful for identifying skeletal metastases by highlighting areas of increased bone turnover. PET-CT combines metabolic information with anatomy, allowing detection of metabolically active cancer across various sites and is commonly used in staging and restaging. Together, these modalities cover the most frequent locations where breast cancer spreads (bone, liver, lungs, distant lymph nodes) and are routinely employed to assess for metastasis. In contrast, ultrasound and mammography are focused on the breast and nearby structures, not a whole-body survey for metastases. MRI is excellent for local extent and some targeted metastatic sites (like brain) but is not the standard first-line modality for broad metastatic workup. Sputum cytology is not relevant to breast cancer metastasis.
