About World Cancer Day

What is World Cancer Day?

A key international cancer awareness day, World Cancer Day takes place every year on 4 February to unite the world to reduce the cancer burden. The Day aims to save millions of lives each year through education, raising awareness and by pressing governments and individuals across the world to take action. 

When is World Cancer Day?

World Cancer Day happens every year on 4 February. In 2024, World Cancer Day will take place on a Sunday. 

Find out more about the origin of World Cancer Day here.

When and how was World Cancer Day established?

World Cancer Day was established by the Paris Charter adopted at the World Summit Against Cancer for the New Millenium in Paris on 4 February 2000. This Charter aimed at the promotion of research for curing as well as preventing cancer, improving services provided to patients, raising awareness among the general public, and mobilising the global community against cancer.

In its article 10, the Charter established that 4 February would therefore be World Cancer Day, so that the Charter of Paris would remain in the hearts and minds of people around the world.

Is World Cancer Day a registered charity?

World Cancer Day is coordinated by the Union for International Cancer Control (UICC) who in turn is a registered charity in Geneva, Switzerland. 

What is/are the official colour(s) of World Cancer Day?

The official colours of World Cancer Day are blue and orange.

What is the theme for World Cancer Day 2024?

The 2022-2024 World Cancer Day theme is: ‘Close the Care Gap’. The first year of the campaign was all about understanding and recognising the inequities in cancer care across the globe. 

The second year was about celebrating progress in its many forms that enable more people to seek and receive the care they need and deserve.

The last year of the campaign is about bringing attention to a higher level– literally – and raise our voices to engage our leaders, asking policymakers and decision makers around the world to prioritise cancer, develop innovative strategies to reduce inequity and invest in achieving a more equitable and cancer-free world. We will call on leaders to eliminate health inequities by addressing the social determinants of health that contribute to them, ensuring that everyone has access to quality health services when, where and how they need them.

Getting involved

Who can get involved?

Anyone and everyone.

From all walks of life, all ages and from all around the word. We’re counting on everyone’s support: individuals, organisations, corporates, schools, cities, governments, hospitals and communities – especially you - because every action counts. 

How can I get involved? 

In whatever way that you can spread the message of World Cancer Day to your family, friends, colleagues, community, media and governments will help us reach the objective of getting as many people as possible to talk, hear, read and learn about cancer.

The Action toolkit is a good starting point for ideas and examples of how to mark World Cancer Day. You might also find some inspiration from what others are doing by browsing the Map of Activities.

How can I volunteer with World Cancer Day?

We are always looking for supporters. One of the best ways to support World Cancer Day is getting involved with your own activity - refer to the Action toolkit to find out how. Another way is to support an existing activity. You may want to check our Map of Activities for activities happening in your local area and to find out how you can get involved. 

If you don’t see any activities near you, we recommend you get in direct contact with your local cancer organisation. Take a look at the UICC member organisations list here.

I’m having trouble with the custom poster / social media tool. Am I doing something wrong?

You’re probably not doing anything wrong. But these tips might help you troubleshoot the problem:

  • If you are uploading an image, make sure your image is a PNG, GIF, JPG or JPEG file.
  • One of the most frequent reasons why the image doesn’t upload is the image size: check that your file isn’t more than 300MB.
  • When you upload your image and the screen turns white, it most likely means your image is too small. We suggest trying with a higher resolution image.
  • If you are adding text to the poster, and the screen turns white, it may be because you have included a special character, like * or @. Sometimes, the tool doesn’t like these characters. Try excluding these characters from your text.

Custom tool still not working? Contact us at hello@worldcancerday.org and we’ll see how we can help.

Do you have a press release?

Every year, we publish a press release for anyone to use to help spread the word. The global World Cancer Day press release will be available publicly on the website before World Cancer Day, and will be available to UICC member organisations under embargo in January.
