search the Arizona Star for "Global Cancer Diagnostics." Not there. http://yellowpages.azstarnet.com/tempe+az/global+cancer+diagnostics/distance.30.n.all-31.zq.html Search everywhere you can think of -- the only place you will find any evidence that GCDx exists is on their GoDaddy website. Face it: Radient and GCDx both exist only on paper. Neither is operational.
