	Biopsy
		Sentinel lymph node biopsy is a procedure in which one sentinel lymph node (sometimes more than one and sometimes just a portion of one) is removed and examined under a microscope to determine whether cancer cells are present.
		Lymph node biopsy can be done surgically (open biopsy) or by needle, depending on the location of the area being tested and the reason it is being tested.
		For a regional lymph node dissection, some of the lymph nodes in the tumor area are removed; for a radical lymph node dissection, most or all of the lymph nodes in the tumor area are removed.

		Lymph nodes act as filters, with an internal honeycomb of reticular connective tissue filled with lymphocytes that collect and destroy bacteria and viruses.
		The lymph node is surrounded by a fibrous capsule, and inside the lymph node the fibrous capsule extends to form trabeculae.
		Virchow's node is a left supraclavicular lymph node which receives the lymph drainage from most of the body (especially the abdomen) via the thoracic duct and is thus an early site of metastasis for various malignancies.

	Imaginis - Lymph Nodes
		Lymph nodes are usually present in clusters in the armpits, on either side of the neck, and in the groin.
		Lymph nodes may also swell from the formation of an abscess (closed pocket filled with pus) in the nodes or if they contain cancer cells.
		The degree to which sentinel node biopsy is effective in determining whether the lymph nodes contain cancer has been shown in research to be directly related to the experience of the surgeon who is performing the procedure.

	Blue Histology - Lymphoid Tissues I
		Lymph nodes are small, flattened, oval or bean shaped organs, which are situated in the course of the collecting lymph vessels.
		The walls of the sinuses can be traversed freely by all components of the lymph, which allows lymphocytes to enter/leave the lymphoid tissue (as part of their constant circulation) or to get in contact with antigens/antigen-presenting cells that may arrive with the lymph.
		Blood vessels enter the lymph nodes through the hilus and travel initially in the connective tissue trabeculae that extend from the hilus into the parenchyma of the lymph node.

	Lymph node staging in gastric cancer
		Preoperative assessment of regional lymph nodes in patients with gastric carcinoma by imaging procedures has a low accuracy (51-68%), thus the N classification is used predominantly in the postsurgical classification (2).
		Moreover the so called lymph node ratio (the quotient between dissected and involved lymph nodes) also appears to be relevant indipendent prognostic factor after an R0 resection (4, 5).
		Fujii et al agree that the category of lymph node metastases based on the TNM system (fifth edition) rather than the Japanese classification proves to be a better indicator with respect to the prognosis of patients with gastric cancer who undergo systematic lymphadenectomy.

	Imaginis - Sentinel Lymph Node Biopsy
		The “sentinel” node is the very first lymph node(s) to receive drainage from a cancer-containing area of the breast.
		Sentinel lymph node biopsy is a new diagnostic procedure used to determine whether breast cancer has spread (metastasized) to axillary lymph nodes (i.e., lymph glands under the arm).
		A standard axillary node dissection, removal of the underarm lymph nodes, usually requires a larger four to six inch incision and a longer recovery period than a sentinel node biopsy.

	Human Anatomy Online
		Lymph leaves the node through the efferent (one-way) lymphatic vessels, which emerges from the hilus, a depression on the concave side of the node.
		All lymph nodes have the primary function of the production of lymphocytes, which help defend the body against microorganisms and against harmful foreign particles and debris from lymph before it is returned to the blood stream.
		The popliteal and inguinal nodes are in the legs and groin, the lumbar nodes in the pelvic region, the axillary nodes in the armpits, the cervical nodes in the chest.

	Lymph Node Dissection Information on Healthline
		Lymph node dissection is done for many different types of cancers, including cancers of the head and neck, breast, prostate, testes, bladder, colon, and lung.
		Lymph node dissection is usually done by a surgeon in a hospital setting, under general anesthesia.
		An accumulation of lymph fluid that causes swelling, a condition known as lymphedema, is the most feared side effect of lymph node dissection.

	Lymph Node Involvement
		When the lymph nodes are involved in the cancer, they are called "positive." When lymph nodes are free or "clear" of cancer, they are called "negative." Your doctors will examine samples from your lymph nodes under a microscope to determine whether any cancer cells have spread there.
		But the extent of disease within a particular lymph node is less important than the total number of lymph nodes affected.
		The more lymph nodes that are involved, the more threatening the cancer may be.

	Lymph Node Biopsy
		A lymph node biopsy removes lymph node tissue to be looked at under a microscope for signs of infection or a disease, such as cancer.

		This picture shows the regions of the lymph node where the blood stream (arteries and veins) anter a typical lymph node.
		For the lymphatic system to function properly in its defensive role, the lymph nodes must be able to "dump" their leukocytes (infection fighting cells) quickly into the general blood stream.

		In a typical procedure, anywhere from 15 to 40 lymph nodes are removed from the underarm on the same side as the cancer.
		Although axillary lymph node dissection helps doctors learn whether the cancer has spread, afterward, many women have side effects such as arm swelling, numbness in the arm, and trouble moving the arm.
		If a woman does not have enlarged lymph nodes under her arm (in which case the surgeon would take them all out) she may be eligible for sentinel lymph node biopsy and should ask about the procedure.
