Cancer is a term used for diseases in which cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. The cancer cells can spread to other parts of the body either through the bloodstream or lymph systems.
If there is a mistake in the code, caused by a mutation, then there is a chance that cells can carry on dividing uncontrollably. There is a rule called the Hayflick constant that suggests once a cell has divided e.g. 20 times, it must commit suicide via a process called apoptosis.
