How Does Cetuximab Work?

Cetuximab works by binding to a receptor in the body called epidermal growth factor receptor (EGFR). EGFR is found in normal skin cells. It is also found in head and neck, colon, and rectum cancer cells.
Normally, certain proteins, such as epidermal growth factor, bind to EGFR and tell cells to grow. By binding to EGFR, cetuximab blocks these proteins from binding, which slows the growth of cancer cells. This medication does not cure cancer, however.
