The congress will take place from 12 to 16 May in Vienna, Austria. Under the theme 'From innovation to action', ESTRO2023 will focus on how to translate and implement research into practice. It will be reflected throughout the programme via state-of-the-art sessions. Along with symposia, debates and teaching lectures, the scientific programme will feature panel discussions and pitch sessions with the aim of increasing interaction between faculty and audience. Joint sessions with partner associations aim to connect delegates with new communities and increase the reach of the ESTRO population. Fostering the development of young radiation oncology professionals remains a top priority for ESTRO and therefore the Young Scientists track will continue to provide educational activities focussed on those in the earlier stages of their careers. https://www.estro.org/Congresses/ESTRO-2023
