Who’s behind World Cancer Day?

World Cancer Day is an initiative of the Union for International Cancer Control (UICC), the largest and oldest international cancer organisation dedicated to taking the lead in convening, capacity building and advocacy initiatives that unite the cancer community to reduce the global cancer burden, promote greater equity, and integrate cancer control into the world health and development agenda.

We believe

We believe that access to life-saving cancer diagnosis, treatment and care should be equitable for all – no matter where you live, what your income, your ethnicity or gender.  

We believe that governments must be accountable and national leadership on policies, legislations, investment and innovation is key to accelerated progress.

We believe that every action matters, whether it is small or big, and that by working together we will create lasting change.
