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 ...
The better-known examples of lymphadenectomy are axillary lymph node dissection for breast cancer; radical neck dissection for head and neck cancer and thyroid cancer; D2 lymphadenectomy for gastric cancer; and total mesorectal excision for rectal cancer. [citation needed]
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]
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.
On clinical examination the skin may be reddened and swollen and a mass felt. Ultrasonography or CT scan will help to establish a diagnosis. Other fluid collections to be considered in the differential diagnosis are urinoma , seroma , hematoma , as well as collections of pus .
The first such trial, led by Umberto Veronesi at the European Institute of Oncology, showed that women with breast tumours of 2 cm or less could safely forgo axillary dissection if their sentinel lymph nodes were found to be cancer-free on biopsy. [26] The benefits included less pain, greater arm mobility and less swelling in the arm. [27]

It typically describes the removal of a tumor or mass and ancillary lymph nodes that may drain the mass, as in radical mastectomy. [2] It is opposed to for example palliative surgery which is intended for symptom relief rather than complete removal of cancer tissue.
