World Cancer Leaders' Summit


What is the World Cancer Leaders' Summit?

The World Cancer Leaders’ Summit is the preeminent annual policy meeting dedicated to furthering global cancer control at the highest levels. The event brings together key decision-makers from around the world and encourages timely debate on emerging issues related to cancer. It provides an important forum to secure a coordinated, multileveled global response to address the spiralling cancer epidemic.

The WCLS is traditionally organised in partnership with the World Health Organization (WHO), the International Agency for Research on Cancer (IARC) and the International Atomic Energy Agency (IAEA), and is hosted by a UICC member from the region where it is being held.

The event is by invitation only, and its attendance is mainly open to UICC members and partners among the global health and cancer leadership community.

Why the World Cancer Leaders' Summit is important

The World Cancer Leaders’ Summit offers global decision-makers are offered a privileged platform to interact, share experience and expertise, and shape how governments, NGOs, civil society, academia and other stakeholders can work to gather and shape the task of eliminating cancer as a life-threatening disease for future generations.

The Summit complements other signature events organised by UICC, which are World Cancer Day and the World Cancer Congress. The Summit plays a pivotal role in this portfolio of global events by ensuring that the nine targets detailed in the World Cancer Declaration to be achieved by 2025 are appropriately recognised and addressed at the highest political levels.


Key objectives of the World Cancer Leaders’ Summit include:

  • Raising awareness among leading decision-makers to ensure cancer is a global health priority.
  • Providing a forum to exchange information and innovative ideas on how to reverse the cancer epidemic and ensure a sustainable response. 
  • Defining compelling messages to support the global call to action against cancer.
  • Creating a force which galvanises politicians and policymakers and increases cancer’s visibility on the international public health agenda.
