Second diagnosis

Hi Im new on these boards. Its frustrating because there are no dierctions. I posted a question but cant figure out how to find it again....but anyway I was diagnosed in 2006 with IDC in left breast. Had lumpectomy, SNB, chemo(ACT), partial rads and tamoxifen.

Last month I was diagnosed with second primary in same breast. Had another lumpectomy and SNB and will have whole breast rads this time.  Path report shows 2.2cm tumor, neg. nodes, clear margins, histologic grade 2, overall grade 1, stage 2a no LVI.

My onc. ordered the oncotype. He said that score will be just one part of the picture and that a low score does not necessarily mean no chemo. This tumor developed and grew while I was on tamoxifen. From what i have read a second diagnosis raises your risk and I have been considered high risk all along and have had yearly MRIs which is what caught this cancer. It never showed up on mammos.

The oncotype results will be in next thurs and I have an apt. with my onc that day to discuss the results. But I am really anxious about the results and waiting is making me crazy. Have any of you had a similar experience? If so, what was your score and subsequent treatment? Thanks, Eileen
