Detailed explanation-2: -The axillary lymph nodes are divided into 3 levels: level I (low axilla) – located in the lower part of the armpit. level II (mid axilla) – located in the middle part of the armpit. level III (high axilla) – located in the upper part of the armpit near the breastbone (sternum)

Detailed explanation-3: -There are five axillary lymph node groups, namely the lateral (humeral), anterior (pectoral), posterior (subscapular), central and apical nodes.

Detailed explanation-4: -See your doctor right away if you notice any changes in your underarm lymph nodes including pain, large size, tenderness, and more.
