      cancer normally develops when there is a genetic (DNA) mistake in a cell which means that it keep dividing instead of stopping like normal cells. Because the cells are form our own bodies often our immune systems don’t recognise them to begin with.

      All living organisms (including you and me!) are constantly making new cells. They make new cells in order to grow and also to replace old dead cells. The process by which new cells are made is called cell division. Cell division is occurring all the time. Around two trillion cell divisions occur in the average human body every day!
      However, if cell division is occurring all the time it has to be well controlled. When cells never stop to divide, they form tumours called cancer.
