Hi Selini,
I feel your pain too. ALL my relitives died from cancer too, except my brother. I'm not sure what your condition is, but if you're really serious about curing with ozone, you need a medical grade ozone generator. The best one costs $1,800 and you get it at http://www.plasmafire.com We use the beta model, and is what cured my wife's cancer. If you want to learn more about ozone, email me again. I have lots of info. on it.
Take Care,
Gaylen
