Hadrontherapy is a particular form of radiation therapy used for cancer treatment. Unlike conventional radiotherapy that uses X-rays, hadrontherapy uses beams of heavy particles, called hadrons.
Thanks to the special physical properties that characterize these particles, hadrontherapy offers potential advantages over conventional radiotherapy because it allows the treatment to “hit” the tumor in a highly accurate and selective way, delivering a lower dose to surrounding healthy tissue and thus reducing harmful side effects and collateral damage. Hadrontherapy also offers the potential for increased biological effectiveness for certain types of typically radio-resistant cancer cells, i.e. those not responding optimally to radiotherapy with X-ray.
