The data below just gives us an idea of what your cancer is all about - makes it easier to answer questions. It's not mandatory but helpful. As for the non rads and chemo - that now makes sense... I'm sure radiation can cause cancer but I would definitely get a second opinion as they should have pinpointed the area in your nasal cavity and likely only scatter hit the other parts. Therefore a lot of your new cancer area was probably low dose and could be radiated again. HBO treatment will also help with healing and infection.... Hugs and good luck.
