Very interesting Lani. Thanks so much for sharing. At my initial diagnosis I was told I was er/pr positive. Also her2 positive. After surgery, (I had sentinel node mapping using blue dye) I was told I was er/pr neg. When the lab in our area was questioned on my positive status they said it was a typo. However, now I am concerned. My oncologist had my hormone receptor status checked a total of 3 times and each time it was negative. However, if the blue dye interferred I wonder now. I forwarded this link to my surgeon for her to check into for me.

Thanks so much for sharing.
