Precision　medicine　(PM)　is　an　innovative　medical　approach　that　considers　differences　in　the　individuals＇　omics,　medical　histories,　lifestyles,　and　environmental　information　in　treating　diseases.　To　fully　achieve　the　envisaged　gains　of　PM,　various　contemporary　and　future　technologies　have　to　be　employed,　among　which　are　nanotechnology,　sensor　network,　big　data,　and　artificial　intelligence.　These　technologies　and　other　applications　require　a　communication　network　that　will　enable　them　to　work　in　tandem　for　the　benefit　of　PM.　Hence,　communication　technology　serves　as　the　nervous　system　of　PM,　without　which　the　entire　system　collapses.　Therefore,　it　is　essential　to　explore　and　determine　the　candidate　communication　technology　requirements　that　can　guarantee　the　envisioned　gains　of　PM.　To　the　best　of　our　knowledge,　no　work　exploring　how　communication　technology　directly　impacts　the　development　and　deployment　of　PM　solutions　exists.　This　survey　paper　is　designed　to　stimulate　discussions　on　PM　from　the　communication　engineering　perspective.　We　introduce　the　fundamentals　of　PM　and　the　demands　in　terms　of　quality　of　service　that　each　of　the　enabling　technologies　of　PM　places　on　the　communication　network.　We　explore　the　information　in　the　literature　to　suggest　the　ideal　metric　values　of　the　key　performance　indicators　for　the　implementation　of　the　different　components　of　PM.　The　comparative　analysis　of　the　suitability　of　the　contemporary　and　future　communication　technologies　for　PM　implementation　is　discussed.　Finally,　some　open　research　challenges　for　the　candidate　communication　technologies　that　will　enable　the　full　implementation　of　PM　solutions　are　highlighted.
