KNOW ALL MARKS THE 5TH WORLD ALL DAY ON SEPTEMBER 20, 2026!

On Sunday, September 20, 2026, we come together to mark World ALL Day, a global campaign aiming to raise awareness of acute lymphoblastic leukemia (ALL) and amplify the voices of patients, as well as the families, caregivers, and communities who support them. The World ALL Day 2026 campaign aims to:

• Help people feel supported, by sharing real experiences of living with ALL, so patients and caregivers can relate to others who truly understand their journey.
• Make it easier for those affected by ALL to find and join supportive communities, including patient groups and WhatsApp chats, where they can ask questions and learn from shared experiences.
• Bring the ALL community together, by encouraging people to share and listen to others, building a sense of belonging and ensuring patients and caregivers are not facing ALL on their own.

For World ALL Day 2026, we’re inviting our community to take part in a simple but meaningful campaign: “Together through ALL”. This will include printing our posters at home or ordering our posters and business cards by contacting us: [email protected]. To help spread the word, display your poster and business cards in a treatment center, hospital, or clinic, or share them with anyone who you think may find our resources useful. Show your further support by taking a photo of the poster on display, perhaps including yourself beside the poster, and share it on your social media channels using our hashtags #KnowALL #WorldALLDay. Don’t forget to tag us!

We are also taking the opportunity through this campaign to raise awareness of places where patients with ALL can share experiences, ask questions, and feel Together through ALL. Join our dedicated WhatsApp group to be part of a community of people living with ALL: https://chat.whatsapp.com/LqjMmDnROVv76a2bdydFf7?mode=gi_t.

If you are short on time, you can also support the campaign by sharing our Know ALL resources for patients and caregivers. We have a wide range of media available, including real-life stories, video interviews with experts and patients, and social media posts. Don’t forget to use our hashtags #KnowALL #WorldALLDay on your social media channels.
Together, we can raise awareness, strengthen connections, and build a more supportive future for everyone affected by ALL.

“My leukemia journey has taught me that no one is meant to face ALL alone. The love, support, and compassion of those who walk beside us make all the difference. Together, we raise awareness. Together, we inspire hope. Together, we stand with every person affected by ALL. Together through ALL."- Jess Olson, Know ALL Ambassador & ALL patient

If you have any questions, please do not hesitate to get in touch via our email or social channels.
