Hi. I am new here. I am 62 years old. I had 2 breast lumps. Both biopsied and one was ER+ invasive breast cancer and other normal tissue. This one was biopsied again as consultant did not believe result. About 6 biopsies taken from front, back, sides and centre of tumor. The results came back invasive breast cancer but triple negative. I was started on EC chemo without much response after 2 sessions. Changed to Docetaxol for 4 sessiions. I then had wide local incision. Final pathology after removal showed clear margins and clear lymph nodes. However this had grown from 13mm to 21mm. Seen my oncologist 3 weeks later to discuss what next because residual Tumor after chemo. Oncologist advised Tumor was not tnbc but actually ER+ so no more chemo required and this is why chemo did not work. While I was relieved I am also struggling to get my head around the difference from core biopsy to final pathology. Has anyone experienced this. I feel I have gone through chemo with all the side effects for nothing. Crying a lot.
