How exactly does herceptin (trastuzumab) work?

Blocks cell growth: Herceptin (trastuzumab) is a "monoclonal antibody". It is a protein that binds to receptors on breast cancer cells called her-2. Her-2 causes breast cancer cells to grow uncontrollably. When Herceptin (trastuzumab) binds to these cells, it slows their growth. However, not all breast cancer cells contain the her-2 receptors. Patients must be tested for the presence of her-2 receptors before they are started on herceptin (trastuzumab). ...Read more

How does herceptin (trastuzumab) work?

Binds to tumor: Herceptin (trastuzumab) is a man-made antibody that binds to cancer cells if they express the her2 receptor.
