Hi,
Information at MayoClinic.com: HER2-positive breast cancer is more aggressive than other types of breast cancer. This type of cancer is less responsive to hormone treatment however, treatments that specifically target HER2 positive breast cancer are effective.
Also, I found a website: Breast Cancer Research
http://breast-cancer-research.com/content/9/3/207
Reading through the article, it appears that for a tumor to be defined as HER2/ NEU positive, 30% or more of the cells are 3+. It is apparent that this specialized test will only pick up breast cancers that are invasive or advanced.
I don't think there are any studies re: HER2/NEU positive findings for non-invasive breast cancer because the test is not designed to detect that type of breast cancer.
Hope this answers your question. Please feel free to contact us again with any further questions.
