7/30/2017what is the difference in treatment and prognosis between to have and not have sentinel node biopsy? What would be just to give treatment to assume there were cancer cells in the node without the biopsy? Can lymphatic nodes catch and filter out cancer cells? if yes, do remove out nodes injury or destructive the lymphatic system though only a few nodes would lose? Any trail to study without lymph node remove for such diagnosis?

7/30/2017removing the sentinel node is done for determining if there is cancer within that node and that information is important for staging and treatment planning. in some cases, the sentinel node is even biopsied before surgery and if positive then chemo may happen first followed by surgery. the amount of chemo and drug options are also influenced by the status of this node. Additionally, it does not destroy the lymphatic mapping system. What can screw that up is a full axillary node dissection which frankly is quire rare today, meaning removal of levels 1, 2 and 3 nodes. today, if more nodes need to be removed, it is usually limited to levels 1 and 2. the body over time does figure out a new lymphatic mapping too. no trials currently for no removing the sentinel node when there is known invasive cancer cells within the breast. sentinel node biopsy has been effective in preventing lymphedema since it removes a node instead of a full ax dissection.
