Good example of the limits of limited biopsy sites. My mom's presurgery needle biopsy referred to heterogeneous mix regarding Her2. If you can have different results within one tumor, it is probably not so rare for multiple met sites to have different characteristics. Did you happen to have neoadjuvant/pre surgery chemo?
