Monoclonal antibodies (MABs) recognise and attach to specific proteins on the surface of cancer cells. These can then stop cancer cells dividing or carry other treatment to fight 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.
