Growth factors are chemicals that trigger a cell to divide. Growth factors are carried through the body in the blood, and they bind to cells whose surfaces contain complementary growth factor receptors. In some cells, there are too many growth factor receptors on the surface, so the cells keep dividing and a tumour forms. Trastuzumab is used to treat some cancers. Trastuzumab acts by attaching to a particular growth factor receptor on a tumour cell. This prevents the cell from dividing and causes the cell to die. What is meant by trastuzumab?
