This is because in geographic tongue, new areas of the tongue become involved with the condition whilst previously affected areas heal, giving the appearance of a moving lesion. The cause is unknown, and
Institute of Physics and Engineering in Medicine Institute of Physics and Engineering in Medicine The Institute of Physics and Engineering in Medicine (IPEM) is the United Kingdom's professional body and learned society for physicists, engineers and technologists within the field of medicine, founded in 1995, changing its name from the Institution of Physics and Engineering in Medicine and Biology (IPEMB) in 1997.
