I must share my experience with using colloidal silver for curing cancer.
My 16 year old dog, Flower, developed a bump on the back of her leg right above her paw. I watched it closely and over the last month it started to change, partly because it started to irritate her and she had been licking it. First, the fur came off, revealing a pink lump. Then the lump started to change. It quickly grew to twice its size and turned different colors, black, yellow and purple, and was developing a few new small bumps at the base of the original one.
So for the last 2 weeks I have been treating her with a high dose of colloidal silver, both orally on an empty stomach 3 to 4 times a day and spraying the area with colloidal silver every chance I could get (she'd see me coming with the spray bottle and would run away). Orally I gave her a tablespoon each time. Of course, the lump grew even larger and uglier with this attack. It even grew tentacle-like things out of the top. It looked very scary.
Anyway, long story short, it finally started to shrink and turned more black on top with the base being bright red. Yesterday, it was pretty shrivelled up and was just dangling by a small piece still attached, and this morning it has fallen off! The skin underneath is bright red and bleeding, but I consider that a good sign as the blood with help filter any remaining toxins from the site.
I will continue giving her silver orally every day and spraying the area with silver until it has totally healed, and maybe for a month or so after that.
