I went to see the surgeon yesterday and it is stage 1 based on tumour size, is 90% estrogen positive , progesterone negative and inconclusive for HER2. I was told that this may be due to not enough of a tissue sample. Next step is MRI and then surgery in about 3 wks. The doctor said she is unsure if it’s ductal or lobular as it was inclusive- again due to the size of the tissue sample.
Thank you to everyone who has taken the time to post some answers. It’s frightening not knowing anything, but at least now I have a plan .
