Sub,
There's another option I doubt you've been told about: LDN, low dose naltrexone.
It put me in remission.
Check out the studies done by Dr. Jill Smith of Penn State.
Also, you can read all about it on the UC Resources pages (there's a long post on it).
It's cheap, not Big Pharma, almost no side effects.
Another big plus for you with LDN is that with your pre-cancerous cells, LDN has been used successfully to treat different cancers.
So, imo this would be the 1-2 punch for you.
