Lymph node extraction and evaluation
Lymph node involvement is an important data to take in consideration. In some cases, lymph nodes are visibly taken by cancer, but in other cases, there’s no apparent involvement. Even patients with negative involvement of their lymph nodes should get an especial lymph node extracted. This lymph node is called sentinel lymph node, and it is a common place of dissemination of cancer. Evaluation of the lymph nodes prior to surgery is performed through ultrasonography, but magnetic resonance imaging might also be helpful.
