Lugano, Switzerland – ESMO Breast Cancer 2025 will take place between 14-17 May in Munich, Germany, bringing together international experts to present and discuss the latest advances in breast cancer research and care. The congress will cover a broad spectrum of topics, from translational research and developments in molecular and functional diagnostics to emerging therapies. Among the key themes are the clinical application of circulating tumour DNA (ctDNA), the evolving role of immunotherapies and antibody-drug conjugates (ADCs), new approaches for managing breast cancer in younger patients.
The event will be accessible both in person and online, with sessions available via live stream on the Virtual Congress Platform.
