[Hadron therapy in carcinoma]

According to some statistics, in the developed countries of west Europe, one in three of population will have an encounter with cancer and, only one in eight of this will have treated by use a linear accelerator. Conventional accelerator-based treatments use photon or electron or proton beams collimated to the tumour place. However, some tumors are resistant on this therapy, while others have complex shapes or are located around vital radiosensitive organs. In those cases it is necessary higher radiobiological efficiency and higher precision. New generation of hadron therapy accelerators are arming with light ions. This therapy is characterized with high precision, in millimeter range over complex volumes. That is also good example how particle physics can benefit medical treatments.
