Our human body is made of trillions of small single nuclei particles called CELLS. Every part of human body even the tiny hairs are formed because of these cells. Even though they are of so much importance to us,still millions of body cells die each day. Nothing to be sad of because our body makes around a billion every day.
Our human body is so complex that even this cycle of dying cells and formation of new one is regulated by it subconsciously. BUT sometimes when the old cells don’t die when they are needed to and body keeps on forming new cells,there is an accumulation of dead cells in body which themselves keep on dividing causing spread of dead cells in body and infection to other organs,creating tumor. This is what we call as CANCER.
