A short history
World Cancer Day is an international day marked on 4 February to raise awareness of cancer and to encourage its prevention, detection, and treatment. World Cancer Day is led by the Union for International Cancer Control (UICC) to support the goals of the World Cancer Declaration, written in 2008. The primary goal of World Cancer Day is to significantly reduce illness and death caused by cancer and is an opportunity to rally the international community to end the injustice of preventable suffering from cancer. World Cancer Day targets misinformation, raises awareness, and reduces stigma.
