The Cancer Researchers to Watch – An Early Career Showcase is a specialized two-day symposium held as part of the Annual Congress of the European Association for Cancer Research (EACR). Designed by and for early-career scientists, the showcase provides a high-visibility platform for the next generation of researchers to present cutting-edge findings in a collaborative environment. The program breaks away from traditional thematic sessions to encourage a broader integration of topics, including tumor heterogeneity, immunotherapy, and advanced bioimaging.
