A member asked:

Is the present of her2 a good or bad prognosis in breast cancer?

Multi-factorial: Prognosis of breast cancer depends on multiple factors. HER2/NEU marker determination is important because of availability of a specific antibody treatment for women with HER2/NEU positive breast cancer.

Both: These tumors are on average more aggressive than their HER-negative counterparts, but also respond to herceptin (trastuzumab) which is very effective.
