All About Cancer
Your body is made up of billions of cells. Each cell has a specific job to do. The picture below shows a single cell clinging on to a surface - in your body it would be holding on to all of its neighbours. Almost every cell has a small bundle of DNA at its core. DNA is the instruction manual telling the cell everything it needs to know about staying alive, repairing damage, being part of a team, and doing its job. In fact each cell has a complete copy of the 23 volume instruction manual for making, maintaining, repairing and running a complete human being. Each cell just uses the bits of the manual that it needs.
