Dictionary of Cancer Terms

View in Spanish: Portador magnético dirigido

Magnetic-targeted carrier (mag-NEH-tik-TAR-geh-ted KAYR-ee-er)
A tiny bead made from particles of iron and carbon that can be attached to an anticancer drug. A magnet applied from outside the body then can direct the drug to the tumor site. This can keep a larger dose of the drug at the tumor site for a longer period of time, and help protect healthy tissue from the side effects of chemotherapy.
