breast cancer recurrence even with very small
breast cancers that are HER2 positive. The data is from the first large study to analyze early-stage breast cancer patients with HER2 positive tumors one centimeter or smaller. All these women would benefit from adjuvant Trastuzumab, also known as Herceptin, (for one year, the standard in America) - along with adjuvant chemotherapy.
