World ALL Day | Know All

This year's campaign

On Sunday, September 20, 2026, we come together to mark World ALL Day, a global campaign aimed 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.

Together through acute lymphoblastic leukemia is a campaign built on connection, understanding, and hope. It aims to remind everyone affected by ALL that they are part of a supportive community, with trusted information, meaningful connections, and practical support always within reach.

Connect.Share.Feel supported.

As part of this year's campaign, we're bringing together a range of resources and peer support opportunities for people affected by ALL. These include patient support groups and a dedicated WhatsApp community hosted by our patient ambassadors. These welcoming spaces provide opportunities to connect with others, share experiences, ask questions, and gain reassurance from people who truly understand the realities of living with ALL.

Get involved

To help raise awareness of ALL, we're inviting our community to take part in a simple but powerful activity. Our Know ALL posters and business cards provide a visible reminder of the support, information, and community that is available for patients and caregivers affected by ALL.

By distributing these materials across treatment centers, hospitals, clinics, and societies, you help ensure that patients encounter trusted resources at crucial moments in their journey, making it easier for them to access education, connect with others, and feel supported when they need it most.

You can order posters or business cards for your treatment center, hospital, clinic, or society by contacting us at SES_KnowALL@ScientificEducationSupport.com. Please let us know the number of A3 posters and business cards you'd like to order and your delivery address – we will be in touch with delivery times.
