About World Cancer Day
World Cancer Day is an international awareness day held every year on 4 February to raise awareness about cancer and to encourage its prevention, early detection and treatment. World Cancer Day is spearheaded by the Union for International Cancer Control (UICC), the largest and oldest international cancer membership organisation dedicated to reducing the burden of cancer.
World Cancer Day happens every year on 4 February. In 2025, World Cancer Day will take place on a Tuesday.
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 is aimed at the promotion of research for treating as well as preventing cancer, improving services provided to patients, raising awareness among the general public, and mobilising the global community against cancer.
In article 10, the Charter established that 4 February would therefore be World Cancer Day, so that the objectives of the Paris Charter would remain in the hearts and minds of people around the world.
World Cancer Day is coordinated by the Union for International Cancer Control (UICC) who in turn is a registered charity in Geneva, Switzerland.
The official colours of World Cancer Day are blue and orange.
The World Cancer Day campaign 2025-27 “United by Unique” explores different dimensions of people-centred cancer care and new ways of making a difference. It will offer a three- year journey from raising awareness to taking action.
Cancer is more than just a medical diagnosis—it’s a deeply personal matter. Behind every diagnosis lies a unique human story - stories of grief, pain, healing, resilience, love and more.
That’s why a people-centred approach to cancer care that fully integrates each individual’s unique needs, with compassion and empathy, leads to the best health outcomes.
The "United by Unique" campaign will begin its journey by inviting individuals from all walks of life to share their personal cancer stories. Much like people-centred care aims to see the individual behind the disease, the campaign intends to showcase real stories with unique perspectives.
Every experience with cancer is unique and it will take all of us, united, to create a world where we look beyond the disease and see the person before the patient. A world where the needs of people and communities are at the centre of health systems.
Getting 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.
Share your story and motivate others to share theirs.
Help us get as many people as possible to talk, hear, read and learn about cancer by spreading the messages of World Cancer Day to your family, friends, colleagues, community, media and governments.
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.
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 events happening in your area and to find out how you can get involved.
If you don’t see any activities near you, we recommend you contact your local cancer organisation.
We sure do! By submitting your World Cancer Day activity on the Map of Activities, you are eligible to receive a digital Certificate of Participation. If you would like to receive your copy, please email hello@worldcancerday.org with the name of the individual or organisation that you would like recognised on the certificate as well as a weblink to your World Cancer Day activity. Please note only one certificate will be sent per organiser.
Please also note that certificates will be provided up until 28 February 2025. Any activities submitted to the Map after this date will not receive a certificate.

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.
