In this article, they describe a new up and coming method for healing pain that many people may not expect - this method being virtual reality.  The concept behind it is that the virtual reality system overtakes the brain and leaves it with no room to process pain sensations.  This method is being tested and used on children with cancer at a Los Angeles Children's hospital, and doctor's say it is a great temporary method to heal pain.  While it may not be a long term solution, it is most definitely a way to take the mind off pain from cancer treatments.  As a doctor who uses virtual reality to treat his patients states, "The device engages multiple senses, essentially flooding the brain with so much input that it cannot register pain signals. When pain messages try to get through, “the brain gives a busy signal,” Hunter Hoffman, director of the VR research center at the University of Washington in Seattle, said."
