I got tongue and lymph node cancer over 1 year ago. I first had radiation and chemotherapy treatment that failed. We found out last April the cancer recurred. I then had an operation which removed the tumor from the base of my tongue and also removed the lymph nodes in my neck. This operation was in June 2006. Severe pain continues. Two MRI and one CT scan tests have been negative for cancer. I had a severe set back last week, when for no apparent reason my lower jaw broke behind my last molar. The doctors say this is either due to severe radiation or the cancer has recurred again. They will be doing a bone biopsy on Monday. If it is positive for cancer the doctors do not show much hope. If it is negative for cancer they are suggesting a major operation. One doctor suggested an outside chance for hyperbaric oxygen therapy to possibly heal the bone. Has anybody out there gone through a similar situation or has any information, as I really need to know more to make a treatment decision.
