The Associação Portuguesa Contra a Leucemia (APCL) is a Portuguese association dedicated to improving the effectiveness of treatment for people with leukaemia and other blood cancers, while supporting patients and their families. Its work combines practical support, information and advocacy with efforts to advance research in Portugal. The association provides resources on blood disorders and treatments, including leukaemias, lymphomas, multiple myeloma, anaemias, bone marrow transplantation and stem cell therapies. It also shares guidance for living well with illness and offers answers to questions from patients and the public.

APCL’s initiatives include the Porto Seguro accommodation project, support for research, and APCL CARES. The organisation raises awareness through campaigns, podcasts, news, personal testimonies and events, including its annual APCL conference. It encourages people to help through donations, membership, volunteering and blood stem cell donor registration, and invites businesses to become solidarity partners. Its website also provides information for healthcare professionals, details of international partnerships, and updates through a newsletter and social media.
