HER2 is a protein that helps breast cancer cells grow and spread, and about 15 to 20 percent of breast cancers are HER2-positive, according to the U.S. National Cancer Institute. Herceptin (trastuzumab) -- one of the newer, so-called targeted cancer drugs -- inhibits HER2. But while Herceptin is a standard treatment for later-stage cancer, it wasn't clear whether it helps women with small, stage 1 breast tumors that have not spread to the lymph nodes.
