As far as HBOT, I had to wait until I had a clear scan, and 6 months after treatment to do it. Some earlier reports suggested it may promote cancer, my doctors seem to think there is some type of risk, and had to visit my oral surgeon a number of times before he finally decided extractions/hbot outweghed the risk, in my case, and had spoken with my RO and ENT. If I didn't really need it, had other options, I would not have any. I read one report that says hbot doesn't promote cancer. Maybe coincidently, but in 2011, a two months after doing HBOT I had a recurrence. You may want to speak with your RO about this.
