About World CLL Day
In 2026, the World CLL Day campaign focuses on Strength in Science. Power in Community., highlighting how advocacy, knowledge, protection and scientific progress can improve the lives of people affected by CLL.

Advocacy that Protects, Support that Empowers
Chronic Lymphocytic Leukemia (CLL) is the most common adult leukemia, yet it remains widely misunderstood. From active monitoring to treatment decisions and long-term care, people living with CLL face unique challenges that deserve greater recognition, support and protection. For World CLL Day 2026, we are highlighting the power of advocacy to protect patients’ rights, improve access to care and ensure that the voices of people affected by CLL are heard. Meaningful support empowers patients, caregivers and families to navigate the CLL journey with greater confidence, connection and hope. Together, we can build a future where no one faces CLL alone.

Turning Understanding into Action
Understanding CLL is only the beginning. Real impact comes when knowledge inspires action: asking questions, making informed decisions, recognising symptoms, exploring treatment options and communicating openly with healthcare professionals. For people living with CLL, better understanding can lead to greater confidence and stronger participation in their own care. World CLL Day 2026 encourages patients, caregivers, healthcare professionals and advocates to turn awareness into practical action, helping to create more informed conversations, better support and improved outcomes across the CLL pathway.

Every Immune System Deserves a Fighting Chance
Living with CLL can affect people in many different ways, but every person deserves timely diagnosis, evidence-based care, appropriate treatment options and the support they need throughout their journey. For World CLL Day 2026, this pillar highlights the importance of protection, equity and access, recognising that no patient should be left behind because of where they live or the barriers they face. By combining science, support and advocacy, we can work towards stronger protection and better outcomes for everyone affected by CLL.

Hope, Health and Hard Science
The future of CLL is being shaped by scientific discovery. From deeper understanding of the disease to innovative therapies and more personalised approaches to care, research continues to create new possibilities for people living with CLL. Science drives progress, innovation changes outcomes, and every breakthrough brings us closer to better quality of life and longer, healthier lives. World CLL Day 2026 celebrates the strength of science and the power of community, because hope is strongest when it is backed by evidence.
2025 Campaign
The 2025 World CLL Day campaign focused on strengthening health literacy, raising awareness, and empowering better decision-making under the tagline “Understand, Decide, Thrive.”
The campaign highlighted the need to better understand the CLL pathway, including active monitoring, invisible symptoms, treatment choices, and ongoing care. It encouraged patients, caregivers, healthcare professionals, advocates, and stakeholders to promote health literacy, support shared decision-making, and empower people living with CLL to take an active role in their care with greater confidence.
2024 Campaign
The 2024 theme was “Level Up” – our call to action to ensure that those with CLL received the same attention, care, and opportunities for treatment as individuals with other types of cancer. However, ‘leveling up’ meant different things to different people and organisations. Some were focused on addressing local inequities specific to their regions. Participants were able to choose from the provided assets to shape their own campaigns. Organisations across various countries identified diverse needs and approaches to ‘leveling up.’ We encouraged all stakeholders to get involved and focus on what mattered most to them.
2023 Campaign
The 2023 campaign focused on the mental health challenges of those living with CLL. Due to a high degree of uncertainty given the challenging nature of the disease, mental health issues and the impact of living with a chronic condition such as CLL are very real. The campaign shone a spotlight on the challenges that CLL patients encounter during the full pathway of their disease – these are particularly high during Active Monitoring (“Watch & Wait”). Living with the immune challenges of CLL can also add emotional and psychological distress, which remained a continued trigger during the beginning of the endemic phase of COVID-19 pandemic. The visual motif and central to all campaign imagery used versions of the umbrella and other symbolism to emphasise support and information needs so as no one has to stand alone.
2022 Campaign
The 2022 campaign was focused to reflect the challenges the CLL community faced as COVID-19 restrictions were lifted across the globe. This was aided within campaign materials by releasing inspiring videos that shared patients’, carers’ and clinicians’ experience of the challenges a CLL diagnosis can bring and what it is like to live and navigate in this later phase of the pandemic. This was carried out with the central campaign theme encouraging everyone to get on board by raising awareness that those vulnerable to infection need to continue to take precautions and still require the consideration of those with a healthy immune system to aid safe navigation in this later phase of the pandemic. The visual motif and central to all campaign imagery remained the umbrella as a vehicle to enable all to get aboard and no one is left behind.
2021 Campaign
In 2021, the first World CLL Day focused a campaign to raise awareness of the vulnerabilities and needs of the immunocompromised during the peak of the COVID-19 pandemic phase. The focus was to acknowledge the importance of society and those with healthy immune systems protecting our community. This was carried out with the central theme showing our appreciation and offering our thanks to encourage wide campaign reach and uptake. The visual motif and central to all campaign imagery was the umbrella, symbolising this as an opportunity to provide information to aid the vulnerable to be shielded by others.
