World Cancer Day 2045

World Cancer Day is marked on 4 February. It promotes reliable cancer information, prevention, timely care and fair access to treatment, while recognising patients, survivors and caregivers.

World Cancer Day is observed on 4 February to bring governments, health professionals, communities and individuals together around cancer prevention, early diagnosis, treatment and care. The date is linked to the Charter of Paris Against Cancer, signed on 4 February 2000 at an international summit in Paris; the charter called for stronger research, better patient care and wider cooperation against cancer. The Union for International Cancer Control later developed the day into a major global campaign. Its message has broadened as knowledge of cancer has advanced: many cancers can be prevented by reducing known risks, vaccination can prevent some infection-related cancers, screening and early detection can improve outcomes, and access to timely diagnosis and treatment remains deeply unequal between and within countries. World Cancer Day therefore combines awareness with advocacy, remembrance and support for patients, survivors, families, caregivers and researchers, while challenging misinformation and stigma surrounding the disease.

Calls for cancer prevention, early diagnosis, equitable treatment, palliative care and respectful support for patients and families.

Evidence-based health education, appropriate screening guidance, patient-support activities and fundraising. Avoid unproven cures and one-size-fits-all screening advice.

Worldwide on 4 February under the Union for International Cancer Control. National screening recommendations and available treatment services vary by health system.
