A lymph node is an oval-shaped organ of the lymphatic system, distributed widely throughout the body including the armpit and stomach and linked by lymphatic vessels. Lymph nodes are major sites of B, T, and other immune cells.ymph nodes are bean or oval shaped and range in size from a few millimeters to about 1â2 cm long. Each lymph node is surrounded by a fibrous capsule, and inside the lymph node the fibrous capsule extends to form trabeculae. The substance of the lymph node is divided into the outer cortex and the inner medulla.
Lymph nodes are small clumps of immune cells that act as filters for the lymphatic system. The lymphatic system runs throughout the body (like the circulatory (blood) system) and carries fluid and cells. If breast cancer spreads, the lymph nodes in the underarm (the axillary lymph nodes) are the first place itâs likely to go. Figure 4.4 shows the location of the axillary lymph nodes. What is lymph node status? Lymph node status is highly related to prognosis. Lymph node-negative means the axillary lymph nodes do not contain cancer. Lymph node-positive means the axillary lymph nodes contain cancer. Prognosis is better when cancer has not spread to the lymph nodes (lymph node-negative) .
