Anyone have low estrogen (ER) breast cancer (PR-, HER2-)?
Anyone else have low ER, PR negative and HER2 negative cancer? It’s a rare subgroup, and can behave more like triple negative. I’m about it have my 6th of 8 chemo sessions and my oncologist wants to try tamoxifen for 5-10 years. He believes that any amount of estrogen will respond to hormonal therapy. My first opinion oncologist was going to do the same but also try to get me on keytruda and was going to throw in Carbo with my ACT. 2nd option (current doctor) said no Carbo and no keytruda- my tumor was 3.5 cm, grade 3 and I’m stage 2b- no lymph node involve or lymphovascular invasion. I’ve had a double mastectomy with failed reconstruction. Just looking for anyone with a similar diagnosis to mine. I think I’m comfortable with my treatment plan. My tumor also has medullary features and was believed to have been a fibroandenoma before the biopsy revealed cancer. No genetic mutations and I’m 41.
