World Cancer Leaders' Summit 2023

The World Cancer Leaders’ Summit (WCLS) is the premier event in global cancer control to help guide and coordinate international, national and regional responses to the cancer epidemic.

The Union for International Cancer Control (UICC) organizes the Summit every two years, offering global influencers from across governments, UN agencies, academia, non-profit organizations and the private sector a unique opportunity to exchange perspectives.

The theme of the WCLS 2023 is "Cancer control in a changing world". It will be hosted by the American Society for Clinical Pathology (ASCP), the American Association for Cancer Research (AACR), the American Cancer Society (ACS), the American Society of Clinical Oncology (ASCO), MD Anderson Cancer Center and Stand Up To Cancer.

The Summit is held in partnership with the World Health Organization (WHO), the International Agency for Research on Cancer (IARC) and the International Atomic Energy Agency (IAEA).
