Which three nodes should you assess if your initial nodal exam suggests malignancy?

• A. Axillary nodes only
• B. Inguinal, femoral, popliteal nodes
• C. Cervical, occipital, supraclavicular nodes
• D. Pectoral nodes, brachial nodes, subscapular nodes

Answer: (D)

The key idea is that when there is suspicion of breast cancer, you systematically check the axillary lymph node basins because they are the first drainage pathway for breast tissue and the common site of early metastasis. Specifically, assess the three axillary node groups: pectoral (anterior), subscapular (posterior), and brachial (lateral). These three areas together cover the main lymphatic drainage routes from the breast, so identifying enlargement in any of them provides important information about nodal involvement and helps guide staging and prognosis. Other regions listed aren’t the primary initial targets for breast cancer nodal assessment. Inguinal, femoral, and popliteal nodes relate more to lower body cancers. Cervical, occipital, and supraclavicular nodes are not the first-line basins for breast drainage, though supraclavicular nodes can be involved in later, more advanced disease.
