The lymph nodes in the neck have historically been divided into at least six anatomic neck lymph node levels for the purpose of head and neck cancer staging and therapy planning.

The mastoid lymph nodes (retroauricular lymph nodes or posterior auricular glands) are a small group of lymph nodes, usually two in number, located just beneath the ear, on the mastoid insertion of the sternocleidomastoideus muscle, beneath the posterior auricular muscle. Their mastoid lymph nodes receives lymph from the posterior part of the temporoparietal region, the upper part of the.

These are often some of the first to be checked by a care provider if he or she suspects a sinus infection. The tonsillar lymph nodes are in the back of the throat and help to drain.
Enlarged Axillary Lymph Nodes and Breast Cancer. Approximately 75 percent of lymph found in the breasts drain into the axillary lymph nodes. As such, the detection of enlarged axillary lymph nodes, especially nodes that are hard to the touch, can play an important factor in the diagnosis, and staging, of breast cancer. Not all cases of breast cancer result in enlarged axillary lymph nodes.
