What are the levels of axillary LNs?
- Level I (low): lateral to pectoral minor
- Level II (middle): deep to pectoral minor
- Level III (high): medial to pectoral minor
In breast cancer, a higher level of involvement has a worse prognosis, but the level of involvement is less important than the number of positive nodes
(Think: Levels I, II, and III are in the same inferior–superior anatomic order as the Le Fort facial fractures and the trauma neck zones; I dare you to forget!)
