Expert Sentinel Lymph Node Biopsy in Darwin by Dr. Maran
In a sentinel lymph node biopsy, one or more of the axillary lymph nodes are removed from the armpit (axilla) to see if there is any evidence that the cancer has spread from the breast to the lymph nodes and therefore, potentially, to other parts of the body.
Usually, if there is no cancer in these sentinel nodes it means the remaining axillary lymph nodes are not likely to contain cancer cells.



Expert Axillary and Targeted Lymph Node Dissection in Darwin by Dr. Maran
During an axillary lymph node dissection, most lymph nodes under the arm (2/3 of the axillary lymph nodes until Level 2) are removed and examined for signs of cancer. This is often done when there is evidence of cancerous spread to the axillary lymph nodes.
The number of lymph nodes involved is part of the staging and helps with treatment planning. Increasingly, there is an option of targeted axillary dissection, where one or two lymph nodes with cancer are clipped before pre surgery chemotherapy followed by localised excision of the affected lymph nodes during surgery.
