In regards to doing HBOT during treatment, it is my experience that with active cancer it is not done, and had to wait two years myself to finally complete my treatments (numerous recurrences), and have a clear scan, even after 3 months, had to wait until six months after radiation, which was around my second clear scan, for them to agree do my extractions with HBOT. There are some that say HBOT can increase risk of cancer spread, through angiogenesis, and some studies say it doesn't. It may have been a coincidence, but 2 months after HBOT in 2011 I had a recurrence. Maybe if the benefit outweighs the risk it may done or if the doctors think it doesn't matter.

All my doctors were involved, in agreement, with the extractions, HBOT process...two RO's, ENT, MO, OS. HBOT doctor required insurance approval, a letter from my ENT, OS prescription, a physical, chest x-ray, medication for high BP.

I hope the helps, and ask your doctors. You may get a different answer.
