HER2+ Percentage

On my FISH test score, it says HER2+ (2.6%) - what does this percentage mean? Is there a percentage from low to high with FISH test score and if so, what are they.

Barbie,
I have often wondered about the scores and have asked but no one has ever really explained it to me, then I asked my oncologist who pretty much said her2 is her2 whether it is high or low. I was told anything over 2.2 is considered positive. I did read somewhere that some oncologist are now saying that anything under 3 is negative but I have not heard that from my oncologist. (Wishful thinking tho). It is so scary looking at all those numbers and not understanding them. Her2 has improved so much since herceptin so try not to worry about the percentage, get the standard of care and hope for the best. Alot of the stuff your read about her2 is outdated, thanks to all of those who did the clinical trials so that we could have the advantage of getting herceptin.Try to stay positive and not worry to much. Take care.

From what I read, 2.6% which is my HER2+ score is considered borderline to low - I heard from someone in England that Herceptin was not given to her as her percentage was 2.7% and considered low, but who knows what is the best way of handling HER2+ - one can only pray we are doing what is best for ourselves. You take care too!!!!
