World Cancer Day is an international day marked every 4 February to raise awareness of cancer, encourage its prevention, and mobilize action to address the global cancer epidemic.

The day is led by the Union for International Cancer Control (UICC) and was established in 2000. By coordinating individual, collective, and governmental action, we all work together to envision a world in which millions of cancer deaths are prevented and access to life-saving cancer treatment and care is equal for everyone, regardless of who you are or where you live.

Every year, hundreds of activities and events take place around the world, bringing together communities, organizations, and individuals in schools, businesses, hospitals, markets, parks, municipal halls, places of worship—on the streets and online—serving as a powerful reminder that we all have a role to play in reducing the global impact of cancer. UICC delivers World Cancer Day campaigns in three-year cycles to enable deeper exploration of a specific theme and to achieve greater impact.

The theme of the World Cancer Day campaign for 2025–2027, “United by Unique,” puts people at the center of care and explores new ways to make a difference. Cancer is more than just a medical diagnosis—it is deeply personal. Behind every diagnosis lies a unique human story—stories of grief, pain, healing, resilience, love, and much more. Therefore, a people-centered approach to cancer care that fully integrates the unique needs of each individual, with compassion and empathy, leads to the best health outcomes. Every experience with cancer is unique, and it will take all of us, united, to create a world where we look beyond the disease and see the person before the patient—a world in which the needs of people and communities are at the heart of health systems.
