4th of February, every year, marks World Cancer Day organised by the Union for International Cancer Control. The theme for this year is 'I am and I Will'. It aims to spread awareness on techniques of prevention, detection and treatment of the illness and acknowledges people's capacity to fight the disease. The day, which is now in its 20th year, seeks to support those who are fighting cancer and reduce its global burden. Some iconic landmarks across the world, like the Calgary Tower in Canada and The Empire State Building, New York City will light up in orange and blue to commemorate World Cancer Day today.
