2. Lymph node biopsy - Wikipedia

   en.wikipedia.org/wiki/Lymph_node_biopsy

   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 ...

3. Sentinel lymph node - Wikipedia

   en.wikipedia.org/wiki/Sentinel_lymph_node

   To perform a sentinel lymph node biopsy, the physician performs a lymphoscintigraphy, wherein a low-activity radioactive substance is injected near the tumor. The injected substance, filtered sulfur colloid, is tagged with the radionuclide technetium-99m. The injection protocols differ by doctor but the most common is a 500 μCi dose divided ...

4. Lymphoma - Wikipedia

   [3] [13] [14] Diagnosis, if enlarged lymph nodes are present, is usually by lymph node biopsy. [1] [2] Blood, urine, and bone marrow testing may also be useful in the diagnosis. [2] Medical imaging may then be done to determine if and where the cancer has spread. [1] [2] Lymphoma most often spreads to the lungs, liver, and brain. [1] [2]

5. Interventional oncology - Wikipedia

   en.wikipedia.org/wiki/Interventional_Oncology

   [1] [2] Interventional oncology has developed to a separate pillar of modern oncology and it employs X-ray, ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) to help guide miniaturized instruments (e.g. biopsy needles, ablation electrodes, intravascular catheters) to allow targeted and precise treatment of solid tumours ...

6. Nodular lymphocyte predominant Hodgkin lymphoma - Wikipedia

   Surgical lymph node excision may be carried out at the time of diagnosis in certain cases such in children diagnosed at an early stage of progression. [15] One study found sustained complete remission in half of the cases with a watch-and-wait strategy after surgical lymph node excision at the time of diagnosis. [15]

7. Lymphovascular invasion - Wikipedia

   en.wikipedia.org/wiki/Lymphovascular_invasion

   Lymphovascular invasion, especially in carcinomas, usually precedes spread to the lymph nodes that drain the tissue in which the tumour arose. Conversely, cancers with lymph node spread (known as a lymph node metastases), usually have lymphovascular invasion. Lymph node metastases usually precede secondary tumours, i.e. distant metastases.
