The removal of one to three axillary nodes for testing is known as what type of procedure?

The procedure referred to is a sentinel node biopsy, which specifically involves the removal of one to three axillary lymph nodes for testing. This technique is used primarily in the context of breast cancer surgery to check for the presence of cancer cells in the sentinel nodes, which are the first few lymph nodes that drain lymphatic fluid from the area around a tumor. Identifying whether cancer has spread to these nodes helps determine the extent of the disease and informs further treatment strategies.

In sentinel node biopsy, the selected nodes are often identified using a tracer dye or radioactive substance to ensure accuracy in locating the sentinel nodes. By limiting the number of nodes removed, this approach aims to reduce the risk of complications and post-operative side effects compared to more extensive surgeries.

Other options, while similar in context, refer to different procedures. Axillary dissection involves the removal of a larger number of lymph nodes, typically more than three, to examine for cancer spread. Lymphadenectomy also refers to the removal of lymph nodes but does not specify the number, generally implying a more extensive procedure. Fine needle aspiration is a minimally invasive procedure used to obtain tissue or fluid samples from specific areas but does not involve the surgical removal of axillary nodes for comprehensive analysis. Understanding these distinctions is essential
