Metal elements offer specific characteristics due to their intrinsic properties and could be used in relation to their final state: a metal complex, a radionuclide, a metal-based nanoparticle product. Transition metal coordination complexes interact with cell molecular targets, affecting biochemical functions resulting in cancer cell destruction. Radionuclides are another way to use metals as anticancer therapy. The metal nucleus of the unstable radionuclide becomes stable by emitting energy. The biological effect in different tissues is obtained by the absorption of this energy from the radiation emitted by the radionuclide, the principal target generally agreed for ionizing radiations being DNA. A new area of clinical research is now emerging using the same experimental metal elements, but in a radically different manner: metals and metal oxides used as crystalline nanosized radiation enhancers particles. The use of metals as a high electron density material tailored at the nanoscale when exposed to radiotherapy is a unique approach that can allow entry to the cell and make feasible the absorption\/deposition of a high-energy dose within the tumor cell (on\/off activity). Therefore, high electron density metal or metal oxide nanoparticles may bring well known physical mode of action, that of radiotherapy, within malignant cells and achieve the paradigm of local cancer treatment.
