A re-excision lumpectomy is performed if the margin is detected to be positive or cancerous cells are very close to the margin. [9] Sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) may be used to determine if the cancer has progressed away from the breast and into other parts of the body. [10]
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 ...
Breast-conserving surgery refers to an operation that aims to remove breast cancer while avoiding a mastectomy. [ 1] Different forms of this operation include: lumpectomy (tylectomy), wide local excision, segmental resection, and quadrantectomy. Breast-conserving surgery has been increasingly accepted as an alternative to mastectomy in specific ...
Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. [1][2] DCIS is classified as Stage 0. [3] It rarely produces symptoms or a breast lump that can be felt, typically being detected through screening mammography. [4][5] It has been diagnosed in a significant ...

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.
Advances in SLN mapping over the past decade have increased the accuracy of detecting Sentinel Lymph Node from 80% using blue dye alone to between 92% and 98% using combined modalities. [10] SLN biopsy is indicated for patients with T1 and T2 lesions (<5 cm) and carries a number of recommendations for use on patient subgroups. [10]
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 treated by surgery, when ...
