Axillary lymph nodes. The axillary lymph nodes or armpit lymph nodes are lymph nodes in the human armpit. Between 20 and 49 in number, they drain lymph vessels from the lateral quadrants of the breast, the superficial lymph vessels from thin walls of the chest and the abdomen above the level of the navel, and the vessels from the upper limb.
Axillary dissection is a surgical procedure that incises the axilla, usually in order to identify, examine, or take out lymph nodes. [ 1] The term "axilla" refers to the armpit or underarm section of the body. [ 2] The axillary dissection procedure is commonly used in treating the underarm portion of women who are dealing with breast cancer. [ 3]
Lymph node dissection. ICD-9-CM. 40.2 - 40.5. [ edit on Wikidata] Lymphadenectomy, or lymph node dissection, is the surgical removal of one or more groups of lymph nodes. [ 1 ] It is almost always performed as part of the surgical management of cancer. In a regional lymph node dissection, some of the lymph nodes in the tumor area are removed ...
The lymphatic system, or lymphoid system, is an organ system in vertebrates that is part of the immune system, and complementary to the circulatory system. It consists of a large network of lymphatic vessels, lymph nodes, lymphoid organs, lymphatic tissue and lymph. [1][2] Lymph is a clear fluid carried by the lymphatic vessels back to the ...
The sentinel lymph node is the hypothetical first lymph node or group of nodes draining a cancer. In case of established cancerous dissemination it is postulated that the sentinel lymph nodes are the target organs primarily reached by metastasizing cancer cells from the tumor. The sentinel node procedure (also termed sentinel lymph node biopsy ...
Central lymph nodes. A central or intermediate group of three or four large glands is imbedded in the adipose tissue near the base of the axilla . Its afferent lymphatic vessels are the efferent vessels of all the preceding groups of axillary glands; its efferents pass to the subclavicular group .
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
66112-4. Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope (see: biopsy). The lymphatic system is made up of several lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph ...
