GRUPO CERO

Group 0, formerly known as AELCLÉS (the Spanish Association of Entities Fighting Leukaemia and Blood Diseases), brings together member organisations supporting people affected by haematological diseases and those who care for them. The association works to make information, support and community resources more accessible to patients, families and caregivers.

Its website provides information about blood cancers and other haematological conditions, including leukaemia, myeloma, lymphoma and AL amyloidosis, as well as topics such as immunotherapy and clinical trials. It also shares guidance on bone marrow donation and transplantation, caregiver support and related health resources. Visitors can find patient and caregiver accounts, data, a directory and map of onco-haematology associations, and details of member organisations.

Group 0 organises activities throughout the year, including patient forums, national meetings, congresses and webinars, and publishes news and a magazine. It also promotes awareness of blood diseases and donation, and offers ways to contact the association and contribute.
