I have ungone surgery for the removal of a recurring breast tumor. This tumor was found in a lymph node. My tumors both were estrogen receptive negative and the core biopsy from the second tumor is invasive ductal adenocarcinoma of breast (grade 2/3) the tumor has a tubular score of 3, nuclear score of 2 and mitotic score of 2. I have been told that I will definitely require radiation.  Since this latest tumor was found within a lymph node does that indicate chemotherapy as well as radiation?

Originally I had the left breast removed followed by reconstruction and prophylactic removal of the right breast a year later a recurring tumor was found in the lymph node under the arm of the left breast area.
