2. Lymph node metastasis - Wikipedia

   en.wikipedia.org/wiki/Lymph_node_metastasis

   Lymph node metastasis is the spread of cancer cells into a lymph node.. Lymph node metastasis is different from malignant lymphoma.Lymphoma is a cancer of lymph node, rather than cancer in the lymph node, because lymphoma originates from the lymph node itself, instead of originating elsewhere (e.g., the breast or colon) and spreading to the lymph nodes.

3. TNM staging system - Wikipedia

   en.wikipedia.org/wiki/TNM_staging_system

   Tis: carcinoma in situ; T0: no evidence of tumor; T1, T2, T3, T4: size and/or extension of the primary tumor; N: degree of spread to regional lymph nodes. Nx: lymph nodes cannot be assessed; N0: no regional lymph nodes metastasis; N1: regional lymph node metastasis present; at some sites, tumor spread to closest or small number of regional ...

4. 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.

5. Sentinel lymph node - Wikipedia

   en.wikipedia.org/wiki/Sentinel_lymph_node

   A blue stained (with isosulfan blue) sentinel lymph node in the axilla. A micrograph showing an adenocarcinoma of the breast (dark pink) in a lymph node (purple) and extending into the surrounding fat (white, chicken-wire appearance). H&E stain. There are various procedures entailing the sentinel node detection: Preoperative planar ...

6. Cancer staging - Wikipedia

   en.wikipedia.org/wiki/Cancer_staging

   3D medical illustration depicting the TNM stages in breast cancer. Cancer staging can be divided into a clinical stage and a pathologic stage. In the TNM (Tumor, Node, Metastasis) system, clinical stage and pathologic stage are denoted by a small "c" or "p" before the stage (e.g., cT3N1M0 or pT2N0).

7. Micrometastasis - Wikipedia

   en.wikipedia.org/wiki/Micrometastasis

   The detection of micrometastases in the sentinel lymph nodes (SLN) is the primary indicator of its spread to the regional lymph nodes, bone marrow, peripheral blood and ultimately to distant metastatic sites, since they are the first of the nodes that cancer would travel to. [3]
