No Touch breast Scan (thermography)

I already started this thread in the High Risk forum, but maybe I will get more responses here.

Just had this scan at my gyno's office, newly approved by the FDA.  It is a type of thermographic screening.  Areas of increased vascularity, possibly indicative of future tumor growth, light up.  I am wondering if anyone else has had this or a similar thermographic scan.  I had a stereotactic biopsy last February on the left breast, at 11:00, that revealed a very small focus of ADH.  The excisional biopsy a month later was completely clean-- the needle biopsy removed it all.  Last May I had a bilateral breast reduction.  Normal mammo last November.

On the scan today, the right side was totally normal, but the left showed some areas that lit up exactly at the spot where the excision was.  My gyno insisted this was because an abnormal vessel that fed the lesion still remains and that it was no need for any concern.  I had been under the impression that everything abnormal had been removed.  Has anyone else here had a similar finding?  I am seeing my BS next week for a regularly scheduled US, so will obviously show her the results and discuss this with her, but in the meantime, although my gyno kept screaming, "This is good news!", somehow I feel uneasy anyway.  If everything is so great, why did any area light up?
