You might also want to try Miracle-Mineral-Supplement (Miracle Mineral Salt) I just got mine today but maybe others on this site will help and also perhaps, Colloidal Silver ?
I'm thinking of attacking the problem on different levels but since I have no expertise I thought I would just suggest a few things.
I do know the Essiac tea helps! It might be good for you too since you're probably under a lot of stress!
I also know the peroxide helps!
So sorry for your situation. I'll hold you & your mum in my prayers!
