A question for my breast buddies

Diseases & Conditions Breast Cancer

I was just looking over some of my reports from the lab and I came across one that says estrogen and progesterone positive which I understand but the HER-2/neu says no overexpression. What does that mean?
 
Thanks for the help.

I believe that means negative for Her 2 neu. A positive score would have said that the oncogene was overexpressed. I am not sure of the scale, it may be 1-4, with 4 being strongly positive. Not sure though, just what I think I remember...
