The South East European International Institute for Sustainable Technologies (SEEIIST) was proposed in 2016 at the World Academy of Art and Science, with the objective of building a facility for charged particle cancer therapy for the South Eastern European countries. SEEIIST will offer the world-class research needed to reduce or even revert the brain drain that is causing a shortage of talent and economic losses in South East Europe. There is no particle therapy in South-East Europe in spite of a growing number of cancers being diagnosed. The facility beam time will be shared 50:50 between treating patients and performing research with a wide spectrum of different light ions beyond the presently used protons and carbon ions, which will make the facility unique in the world. SEEIIST Project is presently in a Conceptual to a Design Phase, implemented with the support of the EU and the involvement of CERN and GSI. The next phase of the project realization will include a final technical design for the facility, a structure and a business plan for the organization and the definition of conditions for the site selection.
