Its been three months since My mothers last RAD treatment. She had her first scan two weeks ago and it showed positive so the ENT Oncologist ordered a MRI on 9/3/14. We received the results yesterday on 9/5/14 and its also shows positive for regrowth. However the ENT Oncologist doesn't want to believe that it is regrowth . He said he is going o get together with the RAD Oncoligist to see what he thinks . in the mean time my mother is in a lot of pain . The ENT oncologist seems to think inflamation could be causing a false positive. What do you think about this anybody
