If cancer is detected in the sentinel node then further treatment is needed. Axillary node dissection involves the excision of lymph nodes connected to the tumor by the armpit (axilla). Radiation is usually used in conjunction with the lumpectomy to prevent recurrence. [11] The radiation treatment can last five to seven weeks following the ...
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 or SLNB) is the identification, removal and analysis of the sentinel lymph nodes of a particular ...
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] The lymph nodes located in the axilla area that are affected by breast cancer are called the guardian or sentinel lymph nodes.
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; in a radical lymph node dissection , most or all of the 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. They are divided in ...
Lymph node metastasis is the spread of cancer cells into a lymph node.. Lymph node metastasis is different from malignant lymphoma.Lymphoma is a cancer of lymph node, rather than cancer in the lymph node, because lymphoma originates from the lymph node itself, instead of originating elsewhere (e.g., the breast or colon) and spreading to the lymph nodes.
The superficial nodes are supplied by lymphatics that are present throughout the arm, but are particularly rich on the palm and flexor aspects of the digits. Superficial lymph nodes of the arm: Supratrochlear nodes: Situated above the medial epicondyle of the humerus, medial to the basilic vein, they drain the C7 and C8 dermatomes.
Simple mastectomy (or "total mastectomy"): In this procedure, the entire breast tissue is removed, but axillary contents are undisturbed. Sometimes the "sentinel lymph node"—that is, the first axillary lymph node that the metastasizing cancer cells would be expected to drain into—is removed. People who undergo a simple mastectomy can ...
