Figure 5c. Axial diagrams show the main drainage pathways (black nodes) of breast cancer to the axillary, internal mammary, and supraclavicular lymph nodes. E = esophagus, Tr = trachea. (a) Diagram shows the axillary nodes (AN), anterior scalene/supraclavicular nodes (ASSCN), and pectoral nodes (PN). ASM = anterior scalene muscle, LCCA = left common carotid artery, LJV = left internal jugular vein, RCCA = right common carotid artery, RJV = right internal jugular vein. (b) Diagram shows the axillary nodes (AN), pectoral nodes (PN), and subclavian chain nodes (SCCN). LCCA = left common carotid artery, LJSCC = left jugulosubclavian confluence, LSCA = left subclavian artery, LSCV = left subclavian vein, RBCA = right brachiocephalic artery, RJSCC = right jugulosubclavian confluence, RSCV = right subclavian vein, TD = thoracic duct. (c) Diagram shows the axillary nodes (AN), internal mammary/retromanubrial nodes (IMRMN), and pectoral nodes (PN). LBCV = left brachiocephalic vein, LCCA = left common carotid artery, LSCA = left subclavian artery, RBCA = right brachiocephalic artery, RBCV = right brachiocephalic vein, TD = thoracic duct.
