Introduction The first EACR conference on Tracking Cancer will highlight the newest approaches to cancer detection and monitoring, from diagnosis through therapy and progression. It will be an interactive environment to discuss current challenges and ways to move the field forward. The meeting will foster the exchange of ideas and spur multidisciplinary collaborations. The programme includes multiple opportunities for networking and interaction. As well as the lively Poster Discussion sessions, there will be Panel Discussions at the end of each day for speakers and participants to engage beyond discussing the data, into envisioning a future that integrates rapidly evolving technologies into basic, translational and clinical cancer research. Who will attend? The conference will bring together those working across technology and data analysis, drug development, and clinical management of cancer. Participation is welcome from PhD students through to group leaders, from both academia and industry, and from the lab to the clinic.
