molecularly targeted therapy
(muh-LEH-kyoo-ler-lee TAR-geh-ted THAYR-uh-pee)
In cancer, a type of treatment that uses drugs or other substances to target specific molecules involved in the growth and spread of cancer cells. Blocking these molecules may kill cancer cells or may keep cancer cells from growing or spreading. Molecularly targeted therapy may cause less harm to normal cells and may have fewer side effects than other types of cancer treatment.
