The World Cancer Congress (WCC) is a major international health conference that encourages effective knowledge transfer and the exchange of best practices amongst global cancer control and health experts.

The event aims to strengthen the action and impact of the cancer community on national, regional and international levels through its educational programme which spans the full spectrum of cancer control - from prevention and treatment to palliative care.

It was awarded 'Best Conference Development' at the 2016 International & European Associations Awards and ‘Best use of social media’ with the 2016 WCC campaign at the 2017 Association Excellence Awards. More recently, the World Cancer Congress 2024 received the Impact Award from the Geneva Tourism & Conventions Foundation in recognition of its positive global impact, bringing together more than 2,000 participants from 122 countries to advance cancer control and collaboration.

The WCC is organised by the Union for International Cancer Control (UICC) and supports UICC’s mission statement 'to unite the cancer community, reduce the global cancer burden, promote greater equity and integrate cancer into the world's health and development agenda'.
