Her2positive

Just wondering if any of you are her2 positive. I was diagnosed Oct will be 2 yrs. My onco did a new biopsy just to make sure there were no changes. We aren't sure if I have always been hert2 positive since my original biopsy did not give that info. I am having a petscan to see exactly were I am now before we start a new treatment. My pets have always been good no new spots just the original places on my spine for 2 yrs he doesnt expect any new places just wants a new on before we start a new treatment I did 15 rounds of ibrance with good results. I understand inbrance is for estrogen positive progesterone positive hert2 negative.
