It acts like "seasoning" for the immune system, attracting immune cells which kill the tumor cells. That's a simplistic explanation, because no one really understands what happens when Herceptin (trastuzumab) binds to tumor cells. There are many theories, but we know immune cells are necessary for it to work. ...Read more

How exactly does herceptin (trastuzumab) work?

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
