Make your mark and save a life: Unite for awareness, stand in solidarity, and empower hope for those affected by blood cancer
Every 27 seconds, someone in the world hears the life-altering words: “You have blood cancer.” Behind those words is a story of uncertainty, treatment, courage, and hope. That hope often lies in the hands of strangers: stem cell donors who selflessly give someone a second chance at life.
On World Blood Cancer Day 2025, we unite under the international message of “Make Your Mark”, a call to raise awareness, show solidarity, and take meaningful action to fight blood cancer. Although an official theme for this year has not yet been announced, the campaign continues to emphasise the power of individual action and collective compassion.
What is blood cancer?
Blood cancer is a general term for cancers that affect the blood, bone marrow, and lymphatic system. It includes:
- Leukaemia
- Lymphoma
- Multiple Myeloma.
These diseases impair the body’s ability to fight infections and produce healthy blood cells. They can strike at any age, and for many patients, a blood stem cell transplant is their only chance of survival.
However, finding a matching donor can be incredibly challenging. That's why raising awareness and increasing the global pool of registered donors is critical.
Why World Blood Cancer Day matters
Deutsche Knochenmarkspenderdatei (DKMS) organises World Blood Cancer Day (WBCD) annually on 28 May to highlight the urgent need for more stem cell donors and amplify the voices of patients worldwide.
The campaign’s iconic symbol, the red ampersand (&), represents connection, unity, and a shared commitment to fighting blood cancer. It reminds us that we are all part of the cure.
Key messages of the campaign include:
- Increasing the number of registered stem cell donors
- Educating the public about blood cancers
- Encouraging conversations and actions that save lives.
How to get involved - Make your mark
No action is too small. Whether you’re an individual, a workplace, or a community group, you can help make a difference this World Blood Cancer Day.
Register as a stem cell donor
Join your local or national stem cell donor registry. If you’re aged 17–55 and in good health, you could be a lifesaving match for someone in need.
Raise awareness on social media
Post the red ampersand (&) symbol with hashtags like #WorldBloodCancerDay, #MakeYourMark, and #BeTheMatch. Share stories, infographics, and videos to inform and inspire your networks.
Host or join a fundraising event
Participate in sponsored walks, virtual events, bake sales, or donation drives. Every penny raised supports donor registrations, education, and research.
Wear red
A simple but powerful gesture to wear on 28 May to show your solidarity with patients around the world.
Conclusion
World Blood Cancer Day reminds us of the transformative power of awareness, action, and altruism. Behind every statistic is a person - a child, a parent, a friend - hoping for a second chance.
You have the power to be that chance.
On 28 May 2025, let’s unite to make our mark, save lives, and spread hope for a world where a blood cancer diagnosis no longer means uncertainty, but recovery, resilience, and renewed life.
