3/26/2017I recently had a lumpectomy. The margins and 2 lymph nodes that were taken all clear. They are sending to lab for mammaprint, and i'm still waiting to find out what it says. One thing (among many) i am a bit concerned about is the ERPR HER2 findings. On the biopsy, it showed ER 30% PR 10% and HER2 negative. What does this mean? I have been told I will likely be put on Arimidex (I'm 58, post menopause) since there was SOME positive response but they aren't "happy" with the lower levels. So I'm wondering, what does this all mean? What does 30% and 10% mean? What is the other 70% and 90%? Of what? Is it a zero sum thing - you're positive or you're not? Also, i don't know how the tumor itself tested... this was the result of the biopsy. Should i know how the tumor tested in pathology? It's not on the report. Am I going to need chemo???

3/26/201730% of the cancer cells were estrogen receptor positive. 10% were progesterone positive. these numbers still represent a positive result and therefore benefit from hormonal therapy. find out if these results were based on biopsy tissue or were they also redone, hopefully, on lumpectomy specimen. request oncotypeDX be done.
