February 4 is the international day of fighting against cancer. Cancer awareness raising aims to enhance awareness and promote timely diagnosis for prevention.  World Cancer Day was established in 2000, at the World Cancer Summit in Paris. At the same time, the Paris Charter was signed to plan cancer-fighting activities and international cooperation. The first official celebration was held in 2005, and since then it has been celebrated every February 4 around the world. The main goal of this day is to unite countries, organizations, and people in a struggle against cancer.
