World Cancer Day is annually observed on February 4 to spread awareness about cancer and the prejudices associated with the condition. Cancer arises when the body's regular control mechanism fails, causing old cells to multiply uncontrollably to generate new, abnormal cells. These additional cells, which travel to other parts of the body, can combine to form a mass of tissue known as a tumour. Despite advancements in medicine, it still remains one of the leading causes of death worldwide. The Broken News Teaser: Jaideep Ahlawat, Sonali Bendre and Shriya Pilgaonkar Turn Modern Day News Anchors for This ZEE5 Project (Watch Video).
