Cell Mutation

Our cells have genes, these genes act like instructions for when our cells multiply. Sometimes when a cell multiplies some of these genes may be damaged or lost, this is a mutation. In some cases this means that the damaged set of instructions may be impossible to follow and the cells can start multiplying in an uncontrolled fashion or not perform their job correctly. After more than six mutations it is possible for a cancer cell to form, when these cells are multiplying uncontrollably it forms a cancerous tumour.
