Definition

A type of radiation therapy. A substance that contains boron is injected into a blood vessel. The boron collects in tumor cells. The patient then receives radiation therapy with atomic particles called neutrons. The neutrons react with the boron to kill the tumor cells without harming normal cells. BNCT is being studied as a treatment for glioblastoma multiforme and recurrent head and neck cancer. Also called boron neutron capture therapy.
