Boron neutron capture therapy (BNCT) is a type of cancer treatment that uses a combination of boron and neutron radiation. In this therapy, a patient is given a boron-containing compound that selectively targets cancer cells. Once the compound is absorbed, the patient is exposed to a beam of neutrons, which interact with the boron to produce high-energy alpha particles that destroy the cancer cells. This treatment is particularly useful for certain types of tumors, such as those in the brain, where traditional therapies may be less effective. BNCT is still being researched and developed, but it shows promise as a targeted approach to cancer therapy, minimizing damage to surrounding healthy tissue.
