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]
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.
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 ...
Subscapular axillary lymph nodes. A posterior or subscapular group of six or seven glands is placed along the lower margin of the posterior wall of the axilla in the course of the subscapular artery. The afferents of this group drain the skin and muscles of the lower part of the back of the neck and of the posterior thoracic wall; their ...
The axillary or inguinal lymph nodes may be enlarged due to the swelling. Enlargement of the nodes lasting more than three weeks may indicate infection or other illnesses (such as sequela from breast cancer surgery) requiring further medical attention. [34] Diagnosis or early detection of lymphedema is difficult.
Radical mastectomy. Radical mastectomy is a surgical procedure that treats breast cancer by removing the breast and its underlying chest muscle (including pectoralis major and pectoralis minor), and lymph nodes of the axilla (armpit). Breast cancer is the most common cancer among women. During the early twentieth century it was primarily ...
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 nodes swell ...
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.
