What I have read on the Budwig diet is that it does help slow down cancer so it it not as aggressive; I have read it has a 90 percent result but only one place. Those that have tried it have reported feeling better that is a good thing - cheap enough and it won't hurt for sure. Anything to slow it down is better than nothing.
So would I use it; would put it in the arsenal. Of course if another treatment does not allow dairy then you can still use the flaxseed with maybe almond milk product? Don't know. But there are treatments like the BX that you have to stay off dairy for at least the first three months.
As for the Cessium - again in doing my research I heard some that have gotten good results although I have seen warnings that you have to know what you are doing because doing it wrong can product adverse reactions. One of the side effects reported is rapid irregular heartbeat that could cause sudden death.

The BX Antitoxin is another treatment, while this treatment is new on pubic radar, it has been used within a research center for well over a decade. The center has treated hundreds, if not thousands by now; many of these survivors can be found, their success stories go back years from cancer to other autoimmune diseases. It is based on five different plants, unaltered and highly concentrated to provide a high energy of the plant's elements. I would is easily classified as homeopathy. The resulting serum targets the bacterium found in ALL cancer cells. You can read more about it at bxhope.com or http://jesichashope.org/bx%20antitoxin.html
There are links to even further information and some pretty graphic videos.
You have options anyone does, it is all about make choices using education first. If you have any questions or need something more holler.
