12 years ago my wife was diagnosed with stage 4 throat cancer. I treated her with B17 {apricot seeds} and baking soda (bicarbonate soda).
She just celebrated her 65th birthday on Tuesday.

With the apricot seeds she ate as many as we could get. I ate the apricots...she ate the seeds, so it was probably 6-8 seeds per day. You can get the seeds online, but I don't know the recommended dosage.
In all honesty, I think the baking soda treatment is what saved my wife. One teaspoon (5mg) of baking soda in water twice a day for two weeks.
It raises the body's ph level to an alkaline state which cancer can not survive in.

Can I put this on my dogs leg that has a tumor that ruptured?

I have pets too and I wouldn't hesitate to use it.
Mix it into a paste...and try to keep your dog from licking it off (or let him lick it off...that won't hurt either). Do some research first and good luck :)
