A radioactive substance is used to dye the sentinel nodes for easy identification and removal. [2] 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).
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.
If cancer cells are found in the nodes, it increases the risk of metastatic breast cancer. Another method of determining breast cancer spread is to perform an endoscopic axillary sentinel node biopsy. This involves injecting a dye into the breast lump and seeing which node it first spread to (the sentinel node). This node is then removed and ...
A sentinel node biopsy can establish cancer staging of the axilla if there are positive lymph nodes present. [5] It is also less risky than performing a lymphadenectomy, having fewer side effects and a much lower chance of causing lymphedema. [5] If cancer is not present in the sentinel lymph nodes, then the axillary lymph node dissection ...
Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope (see: biopsy). The lymphatic system is made up of several lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph nodes swell ...
Another concept is that one of the supraclavicular nodes corresponds to the end node along the thoracic duct and hence the enlargement. [3] Differential diagnosis of an enlarged Virchow's node includes lymphoma, various intra-abdominal malignancies, breast cancer, and infection (e.g. of the arm).
Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
