Two sentinel nodes had microscopic traces of cancer (.4 and .2 mm) an ancillary node was negative. The doctor wants to remove more Lymph nodes. Dr David Chan's book, which I use as a reference, indicated that there is no therapeutic value in doing this so i do not want to go through another surgery. My Oncologist will still treat me, but still want me to go through the other surgery 1st. He said many negative things about Rads and believe I should have a mastectomy. My cancer was .9 cm and clear margins. all my tests results have been good. Has anyone else had this problem??? Onc. said rads can cause lymphodema more so than removal of LN.
