World Cancer Congress

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

Tedros Adhanom Ghebreyesus, WHO Director General speaking via recorded message to the attendees of the World Cancer Congress 2022

The World Cancer Congress 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.

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

The first International Cancer Congress was held in Madrid in 1933. It led to the foundation of the International Union Against Cancer in 1935, renamed the Union for International Cancer Control (UICC) in 2010 and today’s proud winner of the International & European Association Award for Membership Engagement.

The WCC supports UICC's mission statement 'unite and support the cancer community to reduce the global cancer burden, to promote greater equity, and to ensure that cancer control continues to be a priority in the world health and development agenda'.

The event takes place every two years in a different country and is hosted by a local member of UICC.
