At both biopsy and post surgery my HER2 IHC results were between 1 and 2 so they sent to FISH testing and both times FISH said negative. I still have nagging worry about this for the future.. like, my tumor was more aggressive because of this and if some cells escaped that were over amplified the HER2 part would wreak havoc despite hormonal therapy. anyone else feel this way? I honestly don't fully understand the HER2 aspect of things

    Hi Kathy,

    For some good information on what HER2 status means, check out the main Breastcancer.org site's page on HER2 Status in the Your Diagnosis section.

    In addition, you can read about how IHC and FISH tests gather information and what that information means for you.

    We hope this helps!
