This worked for my brother!! So I can attest it works!!! Probably not ALL cancers, but I’ve seen it work! (Brother HAD stage III kidney cancer) he did this on top of raising and lowering his internal body temp with an infrared sauna. His oncologist locally gave him basically a death sentence. He took it upon himself not to do chemo, got a second opinion (advent in Orlando). Set him up for treatments down there. New oncologist said “whatever you did + treatments completely obliterated the cancer. He’s been cancer FREE for a couple years now….. officially he’s in remission but his docs say he’s cancer FREE. Still does PET scan bi- annually.
