The Hellenic Cancer Federation (ELLOK) is the national umbrella organisation of Cancer Patient Associations. It represents 50 Cancer Patient Organisations – members across Greece – advocating for all cancers, including common, rare and paediatric cancers. ELLOK’s overarching activities aim to advocate for cancer policy and research, foster cancer patients’ rights to equal, universal and unhindered access to timely diagnosis, treatment, and care through joining forces with all our members and stakeholders related to cancer care, empower and educate cancer patients, survivors and caregivers to be able to make informed decisions and take an active role in their care and strengthen networking, collaboration and the exchange of best practices with other national and international cancer patient organisations.
