Treatment guidelines for aggressive form of breast cancer

The American Society of Clinical Oncology (ASCO) has released two sets of guidelines for treating patients with an aggressive form of breast cancer. 15-20% of breast cancers are HER2-positive, carrying "high levels of the HER2 protein, which causes tumor cells to grow and divide faster than happens with most other breast cancers." According to Dr. Eric Winer, co-chair of the expert panel that developed the guidelines, doctors now have several treatment options for HER2-positive breast cancer, "all of which are associated with improved survival."
