Neutron capture therapy is a binary system that consists of two separate components to achieve its therapeutic effect. Each component in itself is non-tumoricidal, but when combined they can be highly lethal to cancer cells. 1) Boron compound (b) is selectively absorbed by cancer cell(s). 2) Neutron beam (n) is aimed at cancer site.
Neutron capture therapy was first proposed in the literature in 1936 by Gordon L. Locher, who observed that isotopes with large neutron capture cross sections, such as boron-10, could be accumulated in cancerous tissue and bombarded with thermal neutrons to induce destruction of the cancerous cells.

No cancer therapy is without the risk of side effects. Neutron therapy is a very powerful nuclear scalpel that has to be utilized with exquisite care. For instance, some of the most remarkable cures it has been able to achieve are with cancers of the head and neck. Many of these cancers cannot effectively be treated with other therapies.
Neutron capture is a nuclear reaction in which an atomic nucleus and one or more neutrons collide and merge to form a heavier nucleus. [1] Since neutrons have no electric charge, they can enter a nucleus more easily than positively charged protons , which are repelled electrostatically .
Neutron radiation is also used in Boron Neutron Capture Therapy to treat cancerous tumors due to its highly penetrating and damaging nature to cellular structure. Neutrons can also be used for imaging of industrial parts termed neutron radiography when using film, neutron radioscopy when taking a digital image, such as through image plates, and ...
Scientists have characterized the role of thousands of mutations in the BRCA2 cancer gene, findings that may help reassure worried patients about their cancer risk or guide doctors toward better ...
Fast neutron therapy utilizes high energy neutrons typically between 50 and 70 MeV to treat cancer. Most fast neutron therapy beams are produced by reactors, cyclotrons (d+Be) and linear accelerators. Neutron therapy is currently available in Germany, Russia, South Africa and the United States.
A new study published on Feb. 12 says that eating yogurt could do more than just provide a delicious breakfast or snack – it could prevent colon cancer. In the study, which was published in the ...
