I agree with her. The compression of the pituitary can cause decreases in TSH leading to hypothyroidism.
Ozone is highly effective for malignant tumors, but not so effective for some non-malignant tumors. Although I would still give it a try. The reasons are :
1. There are very few things that will cross the blood-brain barrier to address the tumor safely.
2. Most non-malignant tumors also have microbial origins, and the ozone will cross the blood-brain barrier readily, and is highly effective in killing pathogens.
Therefore I still see it as being the best choice, at least to try first.
Antimicrobials in general are not going to hurt and some may make it in to the brain. Chaparral in particular shows some evidence of possibly passing in to nerve tissue. Immune stimulants like bladderwrack and amla berry would also be good choices.
Otherwise the only other thing I can think of is I have seen a lot of things cured using Rife units used at 666hz.
