There was a recent case of kidney cancer that just gone into remission (a Kidney cancer is unique in that it doesn't respond well to the usual alkalizing remedy such as baking soda, sodium citrate, potassium citrate, sodium carbonate and potassium carbonate. It won't also respond to hydrogen peroxide, blood root or black salve. There's a reason behind it that kidney is a regulator of pH and it can't achieve a uniformly high alkaline remedy. Also the cancer cells in kidney can't be digested by a sanguinaria, bloodroot tincture or black salve, although it does digest surrounding cancers, mostly cancer polyps. The one remedy that did work was based on the theory of fungus causing cancer. Fungus causing cancer is relatively straightforward, certain molds such as black mold fungus, found in most homes produces a cancer causing chemical well known in medical literature called aflatotoxin and mycotoxins. These are also found in the body infected with low concentrations of these in food, water, and sometimes is infected. Therefore the best remedy that I can come up with, including metastatic kidney cancer is the azoxystrobin in the brand product Amistar (there may be many other brands) often sold as fungicide, made from natural substance from a fungicide found in a pine cone, often used to rid of molds and fungus used in grass growing lawn. A kidney cancer usually will go into remission after about 3 - 4 days. The dose I used is fairly low, between 1-2 drops taken 3 or 4 times a day dissolved in 1/2 glass of water. Most of the cancer pain will be reduced in a day, but I think it may take a month to completely rid of them. However, I don't believe a cancer can go away completely and may come back. As a result there are two possible approach to this issue. Take one drop to two as maintenance dose a day, or just wait until I have one and then take it when I needed it. I am a bit conservative and are one of those who will wait and take it on as needed basis to prevent possible resistance of azoxystrobin. At the present, there is no resistance to this. I believe there is a fungus colony, or a mold which could explain why they keep coming back if they are not taken for about a month or two. Most other organs as in prostate cancer might be coming from the same source and the remedy can be used with this same thing. Of course when it is bought, the excuse is to buy as a fungicide for the garden. lol.
