===Ionising Radiation and Cancer===
: Exposure to '''ionising radiation''' is a [[Risk Factor|risk factor]] in [[cancer]] because '''ionising radiation''' can cause [[DNA]] [[molecule]]s to break. When the [[Cell (Biology)|cell]] tries to repair the [[DNA]] it can make mistakes called [[mutation]]s. If this [[mutation]] tells the [[Cell (Biology)|cell]] to replicate constantly then this becomes [[cancer]].
