2. Bladder cancer - Wikipedia

   en.wikipedia.org/wiki/Bladder_cancer

   A bladder cancer case is assigned a stage based on the TNM system. [11] A tumor is assigned three scores based on the extent of the primary tumor (T), its spread to nearby lymph nodes (N), and metastasis to distant sites (M). [13] The T score represents the extent of the original tumor.

3. 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.

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. TNM staging system - Wikipedia

   en.wikipedia.org/wiki/TNM_staging_system

   N1: regional lymph node metastasis present; at some sites, tumor spread to closest or small number of regional lymph nodes; N2: tumor spread to an extent between N1 and N3 (N2 is not used at all sites) N3: tumor spread to more distant or numerous regional lymph nodes (N3 is not used at all sites) M: presence of distant metastasis. M0: no ...

6. Metastasis - Wikipedia

   en.wikipedia.org/wiki/Metastasis

   Cut surface of a liver showing multiple paler metastatic nodules originating from pancreatic cancer. Initially, nearby lymph nodes are struck early. [10] The lungs, liver, brain, and bones are the most common metastasis locations from solid tumors. [10] In lymph node metastasis, a common symptom is lymphadenopathy

7. Sentinel lymph node - Wikipedia

   en.wikipedia.org/wiki/Sentinel_lymph_node

   The axillary lymph nodes drain 75% of the lymph from the breasts((uncited)) and so may be the first lymph nodes affected in breast cancer. The sentinel lymph node is the hypothetical first lymph node or group of nodes draining a cancer. In case of established cancerous dissemination it is postulated that the sentinel lymph nodes are the target ...
