Rosie's correct in that you can't get more RAD in the same place you previously had RAD. To fill in the info about the IMRT, that method is pretty precise as to the placement of the radiation, so If you have IMRT treatment in one area, it's possible to have another treatment in a different area. My case I had IMRT to left side of neck and tongue last November, then again to right side of neck last April. First dose maximum 7000gy, second dose smaller 5500gy.

Hope this helps.
