Yes, I heard radiation is used to relieve pain, as mentioned, by reducing tumor size, and with unhealed wounds, and with bone cancer, that I know of. From my last surgery I still had an open wound, but ENT said radiation will close that up. I also had radiation 3x to the same area, and is being done more often, but it also depends on the total Gy used, the area radiated, and it's maximum toxicity levels of any structures, and if new tissue was used for reconstruction from any flaps, that make it possibly to do reirridation. Good luck with everything.
