In brief: Both

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

In brief: 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. See this site for more information. http://ww5.komen.org/BreastCancer/TumorCharacteristics.html
