I haven't been privy to any tales of tumors being fought with The Master Cleanser
, but I think it may be inappropriate for an 85 year old. Especially since, for that kind of thing, it may require quite a long bout of cleansing.
I think you will have much better luck with maybe an herbal treatment. I wish I knew of some good resources for you, but keep looking on the web through search engines.
Maybe you could find a holistic doctor who would be willing to talk to you about your options. Obviously I don't know what kind of treatment you've sought in the past. But if you believe in alternative medicine that's a good place to look.
A lot of times these things are energy related and massage and acupuncture can alleviate so much. Granted, you may not be in a financial position to indulge these services.
I hope you find something more positive and helpful out there. Sending good energy your way.
