What is the difference between sentinel and axillary lymph nodes?

Axillary dissection removes more nodes and disrupts more of the normal tissue in the underarm area than a sentinel node biopsy. So, it’s more likely to affect arm function and more likely to cause lymphedema. For this reason, sentinel node biopsy is the preferred method to check the axillary lymph nodes.

Can axillary lymph nodes be felt?

Lymph nodes can only be felt in the areas listed: head and neck. arms. axilla (armpits)

Is the axillary vein in the axillary sheath?
