NCIt definition : A halogenated thymidine analogue with potential antineoplastic and radiosensitizing
activities. Bromodeoxyuridine competes with thymidine for incorporation into DNA,
resulting in DNA mutation and the inhibition of cell proliferation. As a radiosensitizer,
this agent is associated with the inhibition of repair of radiation-induced DNA double-strand
breaks.;
Alternative definition : NCI-GLOSS: A drug that makes cancer cells more sensitive to radiation and is also
used as a diagnostic agent to determine how fast cancer cells grow.;
