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.
Radiation therapy kills cancer cells in two ways depending on the effective energy of the radiative source. The amount of energy deposited as the particles traverse a section of tissue is referred to as the linear energy transfer (LET). X-rays produce low LET radiation, and protons and neutrons produce high LET radiation.
He hypothesized that cancer, malignant growth, and tumor growth are caused by the fact that tumor cells mainly generate energy (as e.g., adenosine triphosphate / ATP) by non-oxidative breakdown of glucose (a process called glycolysis). This is in contrast to healthy cells which mainly generate energy from oxidative breakdown of pyruvate.

As in diagnostic nuclear medicine, appropriate radionuclides can be chemically bound to a targeting biomolecule which carries the combined radiopharmaceutical to a specific treatment point. [ 3 ] It has been said that "α-emitters are indispensable with regard to optimisation of strategies for tumour therapy".
The entry and exit of large molecules from the cell nucleus is tightly controlled by the nuclear pore complexes (NPCs). Although small molecules can enter the nucleus without regulation, [ 1 ] macromolecules such as RNA and proteins require association with transport factors known as nuclear transport receptors , like karyopherins called ...
Anastasis can help cancer cells by enhancing their migration, metastasis, and resistance to chemotherapy. [13] [14] The process of anastasis can be one explanation for the survival of cancer cells after they are treated with cytotoxic drugs; apoptotic cells are able to recover via anastasis following the elimination of such compounds.
Most 131 I production is from neutron irradiation of a natural tellurium target in a nuclear reactor. Irradiation of natural tellurium produces almost entirely 131 I as the only radionuclide with a half-life longer than hours, since most lighter isotopes of tellurium become heavier stable isotopes, or else stable iodine or xenon.
