Monoclonal Antibodies:

Antibodies made in the laboratory and designed to target specific substances called antigens. Monoclonal antibodies which have been attached to the chemotherapy drugs or radioactive substances are being studied to see if they can seek out the antigens unique to cancer cells and deliver these treatments directly to the cancer,thus killing any cancer cells without harming healthy tissue. Monoclonal antibodies are also used in other ways, for example, to help find and classify cancer cells.
