in my personal experience, i had lymphoma and prostate cancer 5+ years ago. now i don't. i had no chemo, no radiation, and no surgery.
i'm not a doctor and cannot give medical advice, but i don't think it went away magically. you be the judge.
also, i have not had a cold or flu in the last 5 years, and i got rid of a chronic sinus infection that i had since i was a kid, and thought was normal.
i have never, previously in my life enjoyed such amazing, vibrant living.
if you have an ability with electronics and $100 you can build one yourself, from parts to be had at almost any electronics supply house.
here are schematics and parts lists. http://www.bobbeck.com/pdfs/beck-protocol-handbook.pdf
good luck, i hope you do as well as i have.
