B, you are right about the hyperbaric tx. exacerbating cancer cell growth [we were told John could not have it after breaking his implant because the cancer was still present] So lets hope the Docs are right about "the cancer hasn't returned". My understanding of hyperbaric tx. that it helps with the healing of tissue,skin cells, etc., but I did not know that it could help with radiation side effects on nerve damage in the head and neck.[I could be all wet on this]
Hopefully, you will be albe to get more expert advice if you go to Dana Farber. Amy in the Ozarks
