World Leukemia Day

World Leukemia Day is a global awareness campaign held every year on 4 September that brings together patient groups and supporters from around the world to raise awareness of leukaemia. It is a chance to educate people about leukaemia, its signs and symptoms, and the importance of early diagnosis to improve outcomes for patients.

Why World Leukemia Day matters

Leukaemia affects people of all ages and from all backgrounds, yet its signs and symptoms can be hard to spot. By raising awareness of these signs and encouraging people to get checked early, World Leukemia Day aims to help more people access diagnosis and care at the earliest possible stage.

For people living with leukaemia and their families, this day also highlights the need for understanding, support and better awareness among healthcare professionals and the public alike.

How to take part

You can help raise awareness and join the global community on World Leukemia Day:

  • Learn about the signs and symptoms: Familiarity with early signs can help people seek medical advice sooner.
  • Share information: Use your voice to spread accurate leukaemia facts on social media and within your networks.
  • Use campaign hashtags: Join the conversation using hashtags such as #WorldLeukemiaDay and #BeLeukemiaAware.
  • Support advocacy efforts: Encourage clearer public education and stronger support for people living with leukaemia.

These actions help bring the global leukaemia community together and raise crucial awareness year after year.
