Monoclonal antibodies (MABs)

Monoclonal antibodies (MABs) therapy is where antibodies are created in a lab to treat or fight cancer cells. These are ‘genetically engineered’ proteins that interact with specific proteins on the surface of the cancer cells.

Antibodies are found naturally in our blood and help us to fight infection. MAB therapies mimic natural antibodies, but are made in a laboratory. These are then given either as an injection or through an infusion (drip).

Monoclonal means all one type, so each MAB therapy is a number of copies of one type of antibody.
