As with Susan, I was also wondering who ordered HBOT, assuming HBC was meant the same, since the MO didn't recommend. I know it's used for many medical conditions and injuries, some which are controversial, as Christine mentioned, but it's expensive, and some insurances may not approve it for certain conditions, but it's usually approved by most to help prevent ORN, Osteoradionecrosis, with the Marx Protocol.

I've seen older studies in regards to wether HBOT can spread or cause cancer recurrence, basically from "angiogenesis." Newer reports say no, but most have a caveat that it hasn't "statistically" shown to cause recurrence, but further studies are needed. Some others say it's possible, and another said it actually reduced cancer recurrence.

Anyway, I had HBOT, twice. The first was in 2011, three months after I finished radiation to have a tooth extracted after a clear scan. HBOT was briefly interrupted halfway for a day or two after being hospitalized because I needed a blood transfusion. I don't think I respond well to oxidative stress, chemo and radiation included. The treatment knocked me out, and was like going to radiation treatment every day all over again, and would go home and sleep 4-5 hours after. About a month after I finished, I had a cancer recurrence. Wether the recurrence was related or not, it's not something I wanted to do again, and was always in the back of my mind.

The 2nd HBOT was in 2014 before I had all my teeth extracted, after waiting two years, since I was basically in continuous cancer treatment since my last time with several more recurrences, and all my newer doctors; Oral Surgeon, ENT, 2 Radiation Oncologists, 2 MO, all said I needed to have a clear scan, I actually had two, with no signs of cancer, before HBOT was done.

As mentioned, it knocked me out, maybe it helped briefly with trismus, but otherwise I felt no added benefit, and it didn't help prevent ORN, didn't help the lymphdemia, and it worsened my neuropathy, balance, tinnitus, and vision, but maybe some of the benefit was unseen, but the main reason it was done was to help prevent ORN.

Good luck.
