How is targeted therapy used to treat stage I breast cancer?

ANSWER

Targeted therapy is a newer treatment. About 20% of women with breast cancer have too much of a protein known as HER2 that sometimes makes the cancer spread quickly. Trastuzumab (Herceptin) is a drug that's been approved to treat women with HER2-positive cancer. It stops this protein from making the cancer grow and makes some chemotherapy more effective.
