Personal Health Information Navigator (PHIN)(TM) on Prostate Cancer facilitates access to timely health information in an interactive environment. The Prostate Cancer Knowledge Model accessible via PHIN(TM) aims at exploring a balanced the rationale behind the information on prostate cancer. To express this rationale we use concept maps. All concept maps in this site were constructed using the IHMC CmapTools software. PHIN(TM) is a collaboration effort between Moffitt Cancer Center & Research Institute and the Institute for Human and Machine Cognition (IHMC).
